摘要：

The compound 4[(Ph(3)SbI)(2)O]. I-2 (1) has been obtained by the addition of an I( )solution in acetonitrile containing ca. 5% water to a solution of triphenylantimony in the same solvent. 1 crystallises in the rhombohedral crystal system. The unit cell contains 12 molecules of (Ph(3)SbI)(2)O and four diiodine molecules. The I-2 molecules link IPh(3)SbOSbPh(3)I molecules to form a one-dimensional chain, while the remaining molecules of IPh(3)SbOSbPh(3)I are not coordinated to I-2. The geometry of the IPh(3)SbOSbPh(3)I unit, in which the Sb-O-Sb bridge is linear, is relatively little perturbed upon coordination, but the I-2 unit shows a significant lengthening of the I-I bond compared with free diiodine. This bond lengthening is reflected in the Raman spectrum of 1 which displays nu(I-I) at 174 cm(-1), representing a decrease of 40 cm(-1) from the position of the fundamental vibration of the free diatomic molecule.
