metal-organic compounds
The Sb atom in the title compound, bis(O-ethyl dithiocarbonato-S)phenylantimony(III), [Sb(C6H5)(C3H5OS2)2], is in sixfold coordination to the C atom of the phenyl group [Sb—C 2.163 (3) Å] and five S atoms of three xanthate ligands. Of these, two S atoms form primary bonds [Sb—S 2.5377 (19) and 2.4987 (17) Å] and there are two intramolecular secondary bonds [Sb
S 3.1051 (15) and 2.9981 (16) Å], making the ligands asymmetrically chelating. The final contact is a weak intermolecular secondary bond [SbS 3.905 (2) Å]. The geometry thus described can best be considered as distorted pentagonal pyramidal, but if the antimony lone pair of electrons is stereochemically active, the arrangement becomes pseudo-pentagonal bipyramidal.
