Structure of organoantimony compounds R4SbL (R = Alk, Ar; L - bidentate ligand) (review)

The geometric parameters and characteristics of the molecular structure of organic derivatives of antimony (V) have been analyzed; their general formula is R 4SbL (R = Alk, Ar; L = S,S'-, O,O'-, O,N-, O,S-bidentate ligand), the antimony atom has octahedral coordination and ligands are usually anizobidentate character. The asymmetry of the ligand coordination depends on the nature of the ligand.
