CdS formation upon decomposition of Cd(n-BuOCS2)2 in EtOH and DMF and the crystal structure of Cd(Ph3P)(n-BuOCS2)2 · Ph3P

Abstract

The thermal decomposition of the chelate Cd(n-BuOCS2)2 (I) in EtOH and DMF, either in the absence or in the presence of Ph3P, yields finely disperse CdS particles. Mixed-ligand complex Cd(Ph3P)(n-BuOCS2)2 (II) has been synthesized. Cd(Ph3P)(n-BuOCS2)2 · Ph3P (III) single crystals have been grown. By X-ray crystallography, the crystal structure of III is built of [Cd(Ph3P)(n-BuOCS2)2] mononuclear complex molecules and uncoordinated Ph3P molecules, which reside inside channels formed by complex II molecules. The coordination polyhedron around a Cd atom is a tetragonal pyramid where the base is formed by the four S atoms of the two bidentate chelating ligands n-BuOCS2− and the P atom of the Ph3P ligand is at the axial vertex. In the structure of III, there are supramolecular assemblies of two complex II molecules.
