摘要：

1 : 1 Complexes of diphenyltin dichloride (DPTC) with meso- or rac-bis(phenylsulphinyl)ethane (meso- or rac-BPSE) were prepared. The results of X-ray crystal structure analysis revealed that DPTC meso-BPSE (I) and DPTC rac-BPSE (II) crystallized in different monoclinic space groups. For I, the space group is P2(1)/a, whilst for II, the space group is C2/c. After the complexing reaction, meso-BPSE retains its configuration in crystal I, but one of the sulphur atoms of rac-BPSE in crystal II has dipositional disorder and the occupancies assigned to those positions are 0.5. Although environments of both positions can meet the demands of tetrahedral geometry for the sulphur atoms, their chirality is inverted with respect to each other, which means that about half of the rac-BPSE ligands invert their configuration in the complexing reaction with DPTC.
