Book Description
The present volume in the organogermanium series describes mononuclear compounds containing only germanium-carbon and germanium-hydrogen bonds (Chapter 1.3). Germanium hydrides with other additional non-carbon ligands, such as halogen or oxygen bonded groups, appear in later chapters according to the Gmelin principle of the last posi tion. Compounds with Ge-H and Ge-O bonds have already been described in Volume 5, Section 1.5.1.4, pp. 50/62. The present volume covers the literature to the end of 1992 and includes many references up to 1994. The nomenclature recommended by IUPAC has been generally adhered to. However, compound names were largely avoided, as most of the compounds are presented in tables and are only identified by their formulas. Many of the data in the tables appear in abbreviated form without units; general explanations are given on pp. X/XI. The volume contains an empirical formula index (p. 327) and a ligand formula index (p.341). The editor wishes to express his gratitude to the former author, Professor J. E. Drake, and to Professor J. Satge for his kind advice and fruitful collaboration. Thanks are due also to Dr. A. R. Pebler for editing the English text and to Mr. H.-G. Karrenberg for drawing the numerous formulas and molecular structures.

Book Description
The aim of this compilation has been to provide a comprehensive, non critical source of information concerning organometallic compounds. The scope is limi~ed to the compounds containing at least one carbon-metal bond. The information includes methods of preparation, properties, chemical reactions, and applications. The First Edition comprised the literature from 1937 to 1958. The Second Edition is completely revised and extended through 1964. The literature prior to 1937 was thoroughly covered by E. Krause and A. von Grosse in ''Die Chemie der metall-organischen Verbindungen," Verlag von Gebrueder Borntraeger, Berlin, 1937. Our work consists of three volumes. Volume I contains derivatives of the transition metals of Groups III through VIII of the Periodic Table. Volume II contains derivatives of germanium, tin, and lead. Volume III contains derivatives of arsenic, antimony, and bismuth. The compilation is based on searches through Chemical Abstracts. The collection of references for 1964 was completed before the Subject Indexes to Volumes 60 and 61 of the Abstracts were available; thus some omissions in the coverage of that year are possible. We have attempted to make the .. coverage of the literature complete in order that the compilation may have best ~i1ity to the chemist, chemical engineer, patent attorney, and editor. In the interest of brevity, certain numerical data are omitted, but references to the original literature are given. Yield data are rounded to two significant figures. Wherever possible, tables have been used. The entries in the Bibliography section include references to Chemical Abstracts.

Book Description
Pergamon Texts in Inorganic Chemistry, Volume 14: The Chemistry of Germanium, Tin, and Lead focuses on the properties, characteristics, transformations, and reactions of lead, germanium, and tin. The book focuses on germanium and compounds of Ge(I) and Ge(II). Discussions focus on germanium(II) compounds of phosphorus and arsenic, germanium(II) imide and nitride, monohalides, analytical determination, biological activity, chemical behavior of germanium, and production and industrial use of germanium. The text then elaborates on organogermanium compounds, complexes of germanium(IV), and tin. Topics include nuclear magnetic resonance, chemical properties of tin metal, isotopes of tin, occurrence and distribution of tin, and fluorogermanates and chlorogermanates. The manuscript takes a look at nuclear magnetic resonance, extraction, industrial and commercial utilization, toxicity, and chemical properties of metallic lead. The publication is a vital source of data for researchers interested in the chemistry of lead, germanium, and tin.

Book Description
A very large number of organo derivatives is formed by the Group IV ele ments silicon, germanium, tin, and lead. In comparing the general properties of these elements, Table 1. 1 shows that the first ionization energies decrease (though not in a regular way) with increase in size and atomic number, con sistent with the general increase in metallic character of the elements. Electro negativity values (which have been the subject of considerable controversy) show no clear trend. Although purely inorganic compounds of tin(n) and leaden) are well known, almost all organo Group IV derivatives show an oxidation state of IV. Bonds to carbon become weaker on passing from silicon to lead, as do the element-element bonds themselves. With any particular element M (M = Si, Ge, Sn, or Pb), there is a small decrease in bond energy in the order: M-Ph > M - Me > M - Et. Although accurate data for organo derivatives are lacking, strengths of bonds to other elements probably decrease in the order: M-F> M-O > M-CI > M-H ~ M-N ~ M-S ~ M-Br > M-I, while for a particular element X, the order is: Si-X > Ge-X > Sn-X > Pb-X. It is therefore understandable that reactions leading to Si-F, Si-O, or Si-CI bonds are especially favoured in a thermodynamic sense.

Book Description
Organometallic Compounds and Living Organisms provides information pertinent to the fundamental aspects of organometallic compounds and living organisms. This book discusses the biological effects of organometallic compounds. Organized into 10 chapters, this book begins with an overview of the recognition of methylmercuric compounds as the causative agents of Minamata disease, which has generated intensive research of their toxic effects. This text then examines the number of investigative applications of the biological inertness of silicones. Other chapters consider the capacity of many organometals to deactivate enzymes, which makes these compounds very useful for studying the nature of the enzyme active site. This book discusses as well the use and preparation of organometallurium compounds as imaging agents. The final chapter deals with the formation and cleavage of metal(loid)–carbon bonds, which play significant roles in the environmental transformation and circulation of metal(loids). This book is a valuable resource for chemists.

Book Description
There are an astonishing number and variety of roles that metals play in contemporary medicine. This book contains information on the medicinal uses of inorganics, that is, of elements such as boron, lithium, selenium, to name a few, as well as metal-containing species. In keeping with the notion that healthy mammals rely on (bio-essential) metals for the normal functioning of approximately a third of their proteins and enzymes, a large number of drugs are metal-based and considerable effort is being devoted to developing both second- and third-generation drugs as well as generating novel metal-based drugs. While there is no doubt that there is an emphasis on 'Metallotherapeutics' throughout the volume, the use of metals in medicine is not restricted to metal-based drugs. The following are also covered: non-invasive radiopharmaceuticals Magnetic Resonance Imaging (MRI) mineral supplements From the foregoing and, more importantly, from the contents of the various Chapters, the reader will gain an appreciation of the very real role metal-based drugs play in modern medicine and of the considerable effort being devoted to the development of novel complexes with greater efficacy as therapeutic and diagnostic agents.
