Gmelin Os.Organ.Vbg. Tl A (closed) 1

This volume is the first in a series providing up-to-date information on the chemical and physical properties of mononuclear organoosmium compounds. The first part deals with the 120 compounds known containing alkyl, aryl, acyl, or alkinyl, but no CO ligands. Compounds of this type have attracted wide interest during recent years, as some of them are important intermediates in the activation of C-H bonds by Os complexes. Most of them are square-pyramidically penta-coordinated OsVI complexes or octahedrally hexa-coordinated OsII, OsIV, or OsVI complexes. The second part of the volume describes the 450 Os carbonyl complexes known which contain one CO group and additional heteroatom-bonded ligands, such as H, halogens, O, S, N, or P donors, or boranes. The third and final part is devoted to the 47 compounds known which contain one CO group in addition to alkyl, alkenyl, alkynyl, aryl, or acyl ligands. Two addendums, an empirical formula and a ligand formula index, allow rapid and easy access to the more than 600 compounds in all.
