Determination of the crystal structure and the spectroscopic data of Pd(N, N′ -dicyclopentyldithiooxamide)2

The title compound exhibits a PdS4 coordination geometry, demonstrated by crystallographic and n.m.r. measurements. The bond distances and valence angles of the complex are discussed using the information provided by i.r. measurements. Despite the strong S,S steric hindrance in the compound, the C-C bond distance is shorter in the complex than in the free ligand. The i.r. spectra also provide evidence for strong intramolecular hydrogen bonds.
