Visual Spatial Enquiry explores visual and textual ways of working within spatial research. Architects and spatial thinkers from the arts, social sciences and humanities present rich case studies from remote and regional settings in Australia to the suburbs of Los Angeles, and from gallery and university settings to community collaborations in Mongolia. Through these case studies the authors reappraise and reconsider research approaches, methods and processes within and across their fields. In spatial research diagramming can be used as a method to synthesise complex concepts into a succinct picture, whereas metaphors can add the richness of lived experiences. Drawing on the editors' own architectural backgrounds, this volume is organised into three key themes: seeing, doing and making space. In seeing space chapters consider observational research enquiries where developing empathy for the context and topic is as important as gathering concrete data. Doing space explores generative opportunities that inform new and innovative propositions, and making space looks at ways to rethink and reshape spatial and relational settings. Through this volume Creagh and McGann invite readers to find their own understandings of the value and practices of neighbouring fields including planning, geography, ethnography, architecture and art. This exploration will be of value to researchers looking to develop their cross-disciplinary literacy, and to design practitioners looking to enhance and articulate their research skills.

While the organometallic chemistry of the d-block transition elements has been a flourishing field for the past 25 years, it has only been in the last several years that dramatic activity and progJ'ess has occurred in the area of lanthanide and actinide organometallic chemistry. The f. -element organometallic research effort has been truly multinational and multidisciplinary. In a large number of countries, sCientists have become increasingly interested in the synthesis, reactivity, spectroscopy, and the molecular and electronic structures of f-element organometallic compounds. The backgrounds of these scientists range from organic, inorganic, nuclear, and catalytic chemistry to chemical and nuclear physics. The motivations for the study of f-element organometallics have been equally varied. In the area of basic research, there has been a growing realization that the lanthanides and actinides represent two unique and, to a great extent, neglected families of elements in which many fascinating aspects of chemistry and bonding remain to be explored. On a more practical level, an increasing number of these elements play important roles in nuclear energy production and in industrial catalytic processes. It has become apparent that efficiency and safety in both areas could greatly benefit from increased knowledge. In the past there has been no suitable international forum available for bringing together researchers in the diverse areas of f-element organometallic science mentioned above.

This dissertation develops f element chemistry by investigating and comparing the synthesis, coordination chemistry, and reactivity of lanthanide and actinide metal complexes with diazoalkane derivatives and guanidinates. The bis(cyclopentadienyl) ligand unit, [(n5-C5ME5)2]2-, was used to conduct these studies since it has previously proven to be a reliable route for investigating new ligands in f element chemistry. This is because it is relatively inert, provides solubility and stability to the reactive metal center, and allows spectroscopic and structural data to be obtained that is useful for analyzing this chemistry. Diazoalkanes, RRLCN2, are of interest because they are important organic substrates that are useful as carbene precursors and as reagents for the synthesis of heterocyclic compounds. Although the chemistry of diazoalkanes with the transition metals has been heavily studied, little is known about f element chemistry with these compounds. The lanthanides and actinides are different in their behavior with diazoalkanes. Lanthanides make cyanoamide complexes that can be converted by their reaction with nitriles to complexes of 1,2,3-triazoles, which are heterocycles with pharmaceutical, industrial, and agrochemical applications. In contrast, uranium makes very soluble products that do not react with nitriles. A facile synthetic route to hydrazonato complexes was also developed from lanthanide allyl complexes and diazoalkanes during this study. The chemistry of the bicyclic guanidinate ligand, (hpp)1-, was examined with the f elements because this ligand has the potential to stabilize higher oxidation states which are rare with the f elements. The (hpp)1- ligand can be readily incorporated into complexes of Ln3+, U3+, and U4+ and it can stabilize rare examples of mono-alkyl, hydride, and "tuck-in", (n5:n1-C5Me4CH2)2- U4+ complexes as well as U5+ in some cases. The reactivity of the uranium "tuck-in" complex was examined because this unit is frequently proposed as an intermediate in mechanistic schemes involving alkyl C-H bond activation with the f elements. The effect of the {(C5Me5)2(hpp)}3- ligand combination on uranium mono-alkyl and hydride reactivity was also examined. Altogether, the results from these studies expand our knowledge of f element chemistry and highlight the differences in chemical reactivity of the f elements compared to the transition metals.

The symposium which provided the incentive for this volume was conducted in San th Diego, California as a part of the 207 National Meeting of the American Chemical Society, March 13-17, 1994. It was conceived partly to continue an informal decennial sequence of sym posia dedicated to the topic off element separations. A lot has changed in the world of f ele ments over the last ten years, precipitating a change in emphasis which should be evident to most practitioners in the field. Production and reprocessing of nuclear fuels are no longer the principal drivers of f element separation technology. Separations technology for environment restoration, waste disposal, and the preparation of high purity lanthanides are now the defming parameters in this important field. These imperatives are reflected in the contributions to this volume. The symposium itself must be considered a success, as the attendance at all sessions was above expectations, despite the fact that it was conducted on the last two days of a large five day meeting. Our thanks to the speakers for their quality presentations, and to the audience who persevered to the end of a long meeting and against the temptation of the excellent weather of San Diego in the springtime. A complete list of symposium participants is given in Appendix 1. Preparation of this volume has been a relatively painless undertaking, largely as a result ofthe high quality ofthe submitted papers.

The lanthanides and actinides (the f elements) are rarely studied in detail by chemistry undergraduates. More often they appear as an afterthought in bonding, spectroscopy, magnetism, coordination chemistry, and organometallics courses. This is largely because of a lack of an accessible text treating the chemistry of these elements in one cover. Moreover, the placement of lanthanides and actinides in the closing pages of standard inorganic chemistry text books serves to marginalise these elements further. The f elements has therefore been written to fill a gap in the undergraduate chemistry textbook market. It covers much of the fundamental chemistry of the lanthanide and actinide elements, including coordination chemistry, solid state compounds, organometallic chemistry, electronic spectroscopy, and magnetism. Many comparisons are made between the chemistry of the lanthanides and actinides and that of the transition elements, which is generally much more familiar to undergraduate chemistry students. The book uses the chemistry of the f elements as a vehicle for the communication of several important chemical concepts that are not usually discussed in detail in undergraduate courses, for example the chemical consequences of relativity and the lanthanide and actinide contractions. Many important modern applications of f element chemistry, e.g. the use of actinides in nuclear power generation and of the lanthanides in magnetic resonance imaging and catalytic converters in motor vehicle exhausts, are also discussed in depth.

The past decade has seen a dramatic acceleration of activity and interest in phenomena surrounding lanthanide and actinide organo metallic compounds. Around the world, active research in organo-f element synthesis, chemistry, catalysis, crystallography, and quantum chemistry is in progress. This activity has spanned a remarkably wide range of disciplines, from synthetic/mechanistic inorganic and organic chemistry to radiochemistry, catalytic chemistry, spectroscopy (vibra tional, optical, magnetic resonance, photoelectron, Mossbauer), X-ray and neutron diffraction structural analysis, as well as to crystal field and molecular orbital theoretical studies at the interface of chemistry and physics. These investigations have been motivated both by fundamental and applied goals. The evidence that f-element organo metallic compounds have unique chemical and physical properties which cannot be duplicated by organometallic compounds of d-block elements has suggested many new areas of endeavor and application. For these reasons, a great many scientists felt the need for some international forum devoted exclusively to the subject of lanthanide and actinide organometallic compounds. In September of 1978, a NATO Advanced Study Institute entitled, "Organometallics of the f-Elements," was held at the SOGESTA Conference Center near Urbino, Italy. It was the universal feeling of the partic ipants that this first meeting was a great success and that vital international communication and collaboration had been stimulated. The principal lectures at this Institute were published by Reidel in 1979 as part of the NATO ASI Monograph Series ("Organometallics of the f-Elements," T. J. Marks and R. D. Fischer, editors).
