ChemInform Abstract: The Coordination Chemistry of Silyl-Sulfurdiimides.

ChemInform Abstract

The reactivities of the title compounds (I) and (III) are investigated. (III) is obtained from (Ia) and (II) by elimination of Me₃SiCl. The X-ray structure of (III) (space group P1, Z=2) reveals a planar S₂N₂ chain. The reactions of these compounds with chlorophosphine Pt complexes proceed only in the case of (IV) with (III) to (V), characterized by IR, NMR, and X-ray crystallography (P2₁/c, Z = 8). In this complex the backbones of the cis diimido ligands are trans-axial relative to the coordination plane resulting in apical Pt···S contacts. The Pt-complex (VI) reacts with the sulfurimides (I) to yield (VII).
