This formula index contains the compounds of all three volumes. The molecular formulae show metal atoms first, followed by carbon, hydrogen, and other nonmetal atoms arranged alphabetically. The monometallic and homo- polymetallic compounds are followed by hetero-bimetallic, -trimetallic, and -polymetallic compounds. Heterometallic compounds are listed under each metal. To make the use of the index easier, for the most part, simplified linear structural formulae are given after the molecular formulae. In the case of compounds containing complicated structures, such as fused carbocyclic, hetero- cyclic, or spiro rings, index names or a combination of group symbols and the parent compound names are used. Polymeric compounds are listed under their monomer formulae. Arseno, antimono, and bismutho compounds appear under their monomeric formulae. Arsenomethane and arsenobenzene, which were isolated as a pentamer and hexamer, respectively, and also as oligomers, are listed under their monomeric formulae and under Ass and Ase, respectively. The reference fiven at the end of each entry includes the volume number under- scored, followed by the page number. An asterisk following a reference page number signifies that the name or formula of this compound in the text was corrected. The lists of corrections and additions to the three volumes are appended to this volume. Several compounds missed in the main body of this index are compiled in the "Additions" section. We wish to express our appreciation to Mrs. Mary Alice Doiron for her perse- verance shown in the preparation of this typescript.

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."
