Article abstract of DOI:10.1016/S0022-328X(00)83484-1

Infrared data suggest that diphenylantimony acetate has a polymeric structure with bridging acetate groups which is partially broken down in carbon tetrachloride solution and completely destroyed in chloroform.The solid state structure has been determined by X-ray crystallography.The compound is triclinic, space group P<*>, with a 10.61(1), b 13.36(1), c 11.07(1) Angstroem, α 106.9(1), β 116.7(1), γ 93.7(1) deg and Z=4.The two independent antimony atoms are linked into polymeric chains by bridging acetate groups and are in pseudo trigonal bipyramidal coordination.The two phenyl groups (mean Sb-C, 2.155 Angstroem) and the antimony lone pair occupy the equatorial positions while one axial position is occupied by an oxygen of the bonded acetate group (Sb-O, 2.137 Angstroem).The bridge bonds occupy the second axial position leading to distances of 2.592 and 2.513 Angstroem to Sb(1) and Sb(2).
