THE BONDING OF THIAZOLES TO PLATINUM(II) COMPLEXES - X-RAY CRYSTAL STRUCTURE OF CIS- AND TRANS-[PT(DIMETHYL SULFOXIDE)(THIAZOLE)CL-2]

摘要

The crystal structures of neutral cis- and trans-[Pt(dimethyl sulfoxide) (thiazole)Cl-2] have been determined by X-ray diffraction. The longer C4-C5 bond distance of the N-coordinated thiazole in both the square planar complexes, as compared to the free ligand, is interpreted in terms of a negative charge density transfer toward the antibonding orbital system of the thiazolic ring.
