The present volume describes organoberyllium compounds containing at least one berylli um-carbon bond, except the beryllium carbides and cyanides. It covers the literature com pletely to the end of 1986 and includes most of the references up to mid-1987. This Gmelin volume is different from all other volumes of the series on organometallic compounds in that it is dedicated to an area of research which has virtually come to a complete standstill. Organoberyllium chemistry has never been a very popular field, and only few workers have contributed to its slow growth, as is seen by the relatively small number of publications in the field. This very modest development became stagnant in the early 1970''s and was followed by a rapid decline. This exceptional fate of a branch of organometallic chemistry is only partly due to the very limited number of potential application~ of beryllium and its compounds. The compounds of this element are, in principle, at least as interesting and intriguing to scientists as those of other metals in the Periodic Table. No doubt the main reason for the apparent ban of all experimental organoberyllium chemistry is to be found in the established, and alleged, hazardous properties of beryllium compounds. Although similar hazards have been established for other organometallics where active research is still in process, e. g. , mercury and lead, these observations were absolutely lethaI for organoberyllium research.

This fifth volume on organoantimony compounds continues the description of pentavalent antimony compounds and concludes the entire series. The treatment of pentavalent compounds with three Sb-C bonds began in Part 4 with the RSbX type and is now completed with types RSb(X)Y, RR'SbX , RR'Sb(X)Y, 3 2 3 2 2 2 RR'R"SbX (Section 2.5.1) and the corresponding bi- and trinuclear compounds (Sec- 2 tions 2.5.2, p.87, and 2.5.3, p. 132). R, R', and R" denote different organic groups bonded through carbon to the antimony atom. X and Y represent inorganic or organic groups that are bonded to antimony by an atom other than carbon. R, X, and/or Y can also be chelating ligands. The remaining part of the volume completeLy covers all pentavalent antimony compounds containing two Sb-C bonds (RSbX , RSb(X )Y, RR'SbX , RR'Sb(X )Y, bi- and tetranucLear 2 3 2 2 3 2 compounds, Chapter 2.6, p. 134) and those containing one Sb-C bond (RSbX , RSb(X )Y, 4 3 RSb(X)Y , bi- and trinucLear compounds, Chapter 2.7, p. 237). These compounds form ad- 2 2 ducts with Lewis bases (symbol D) and form many ionic compLexes by the addition of saLts such as amine hydrochLorides (symbol MZ).The adducts and ionic compLexes are described immediately after the parent substances. The volume concludes with an Empirical Formula Index (p. 318) and a Ligand Formula Index (p. 357).
