Coordination chemistry of thiocarbonyl ligand

Abstract

The first transition-metal thiocarbonyl complexes were discovered just over 20 years ago. Since then, numerous thio-, seleno-, and even one tellurocarbonyl complex, have been reported. The physicochemical properties of these complexes have been examined and it is now generally accepted that the net e1ectron-withdrawing capacities of the cha1cocarbonyl ligands increases in the order CO < CS < CSe. The history and development of the coordination chemistry of the these ligands will be briefly reviewed with particular emphasis being placed on the CS ligand and our own recent work on the chemistry of chromium thiocarbonyl compounds. © 1988 IUPAC
