Abstract

The complexes Sb(S2COEt)2X (X = Cl, Br, I) and Bi(S2COEt)2X (X = Cl, Br) have been isolated as cystalline compounds. From infrared spectra and molecular weight determinations it is concluded that they are polymeric in the solid state but dissociate in solution. An X-ray structure determination of Sb(S2COEt)2Br shows that the antimony atom is six coordinate, with the bromine atoms forming bridges between pairs of antimony atoms leading to a zigzag chain. The unit cell is monoclinic, space group P21/c, with a = 10.769(2), b = 16.462(2), c = 8.360(2) Å, and β = 110.71(2)°. © 1983.
