摘要：
Complexes Ph-3(C2H4O2)SbDMSO (I), (3-FC6H4)(3)(C2H4O2)SbDMSO (II), and (4-MeC6H4)(3)-(C6H4O2)SbDMSO (III) are synthesized by the reactions of triarylantimony with ethylene glycol or pyrocatechol in the presence of an oxidant and dimethyl sulfoxide (DMSO). According to the X-ray diffraction analysis data, the Sb atoms in the complexes have the coordination of a distorted octahedron with the chelate cycle (C2H4O2 or C6H4O2) and two aryl groups in the equatorial plane, and the third aryl group and DMSO molecule occupy the axial positions. The CSbO axial angles are 173.59(5)degrees (I); 175.96(8)degrees, 175.93(8)degrees (II); and 174.07(8)degrees (III). The Sb?=SMe2 distances (2.346(2)-2.407(2) angstrom) considerably exceed the sum of covalent radii of the atoms.
