The 9th Jerusalem Symposium was dedicated to the memory of Professor Ernst David Bergmann. An imposing and deeply moving memorial session, chaired by Professor Ephraim Katzir, the President of the State of Is rael and a close friend of Professor Bergmann preceded the Symposium itself. During this session, Professor Bergmann's personality, scien tific achievements and contributions to the development of his country were described and praised, besides President Katzir, by Professor A. Dvoretzky, President of the Israel Academy of Sciences and Humanities, Professor D. Ginsburg, Dean of the Israel Institute of Technology in Haifa and the author of these lines. May I just quote short extracts from these speeches. President Katzir: "As we open this ninth in the series of symposia initiated in 1967, it is difficult for me as, I am sure, for many of Ernst Bergmann's friends, co-workers and students, to be here without him. He was not only a great scientist and a beloved teacher, he was one of the most important founders of science in this country. To him we owe many institutes and the establishment here of many branches of science. " Professor Dvoretzky: "Ernst Bergmann's greatness did not stem from one component overshadowing all the others. It was a multifaceted great ness consisting of the harmonious co~lescing of seemingly contrasting entities into a wonderful unity ••.

Metal ions play key roles in biology. Many are essential for catalysis, for electron transfer and for the fixation, sensing, and metabolism of gases. Others compete with those essential metal ions or have toxic or pharmacological effects. This book is structured around the periodic table and focuses on the control of metal ions in cells. It addresses the molecular aspects of binding, transport and storage that ensure balanced levels of the essential elements. Organisms have also developed mechanisms to deal with the non-essential metal ions. However, through new uses and manufacturing processes, organisms are increasingly exposed to changing levels of both essential and non-essential ions in new chemical forms. They may not have developed defenses against some of these forms (such as nanoparticles). Many diseases such as cancer, diabetes and neurodegeneration are associated with metal ion imbalance. There may be a deficiency of the essential metals, overload of either essential or non-essential metals or perturbation of the overall natural balance. This book is the first to comprehensively survey the molecular nature of the overall natural balance of metal ions in nutrition, toxicology and pharmacology. It is written as an introduction to research for students and researchers in academia and industry and begins with a chapter by Professor R J P Williams FRS.

This book provides researchers in the fields of organic chemistry, organometallic chemistry and homogeneous catalysis with an overview of significant recent developments in the area of metal-ligand cooperativity, with a focus on pincer architectures. The various contributions highlight the widespread impact of M–L co-operativity phenomena on modern organometallic chemistry and catalyst development. The development of efficient and selective catalytic transformations relies on the understanding and fine control of the various elementary reactions that constitutes a catalytic cycle. Co-operative ligands, which actively participate in bond making and bond breaking together to the metal they support, open up new avenues in this area. In particular, buttressing a weak or reactive metal-ligand bond by flanking coordinating arms in a pincer ligand design is proving a versatile strategy to access robust metal complexes that exhibit unusual and selective reactivity patterns.

To appreciate the chemistry and physical properties of complexes of the transition series, an understanding of metal-ligand interactions applied to complexes of the d-block is needed. Metal Ligand Bonding aims to provide this through an accessible, detailed, non-mathematical approach. Initial chapters detail the crystal-field model, using it to describe the use of magnetic measurements to distinguish complexes with different electronic configurations and geometries. Subsequent chapters look at the molecular orbital theory of transition metal complexes using a pictorial approach. Bonding in octahedral complexes is explored and electronic spectra and magnetic properties are given extensive coverage. The material addressed in this book forms the foundation of undergraduate lecture courses on d-block chemistry and facilitates learning through various key features, including: full colour diagrams; in-text questions with answers; revision exercises and clearly defined learning outcomes to encourage a reflective approach to study; an associated website; and experimental data and observations from everyday life. A basic knowledge of atomic and molecular orbitals as applied to main group elements is assumed.

In September 2002, a NATO-ASI was held in Cetraro (CS), Italy on the theme of "Metal-Ligand Interactions in Molecular-, Nano-, Micro-, and Macro-systems in Complex Environments". This event has followed the previous ones held in the same place in 1991, 1994 and 1998. In the present and the previous schools a broad interdisciplinary cross-section of experimental and theoretical researchers, interested in a better understanding of metal-ligand interactions from different viewpoints, was linked together to exchange experience, to review the state-of-the-art, to indicate new techniques and methods, to explore new fields and perspectives. Particular emphasis was given to the problems related with the crossing from molecular systems to nano-, macro-and micro-scale materials and to the effects of the environment on the properties of the molecular systems. The school was organized around lectures and special research seminares given by leading experts in the following fields: • metal clusters • inorganic complexes and materials • surface phenomena • adsorption and catalysis • organic and bio-inorganic systems • ab initio theory • density functional theory • classical and quantum dynamics This volume contains the formal lectures and selected contributed papers and describes the main aspects and problems tackled during the 12 days of the event.

Metal-ligand interactions are currently being studied in different fields, from a variety of points of view, and recent progress has been substantial. Whole new classes of compounds and reactions have been found; an arsenal of physical methods has been developed; mechanistic detail can be ascertained to an increasingly minute degree; and the theory is being developed to handle systems of ever-growing complexity. As usual, such multidisciplinarity leads to great opportunities, coupled with great problems of communication between specialists. It is in its promotion of interactions across these fields that Metal-Ligand Interactions: From Atoms, to Clusters, to Surfaces makes its timely contribution: the tools, both theoretical and experimental, are highly developed, and fundamental questions remain unanswered. The most fundamental of these concerns the nature of the microscopic interactions between metal atoms (clusters, surfaces) and ligands (atoms, molecules, absorbates, reagents, products) and the changes in these interactions during physical and chemical transformation. In Metal-Ligand Interactions, leading experts discuss the following, vital aspects: ab initio theory, semi-empirical theory, density functional theory, complexes and clusters, surfaces, and catalysis.
