Abstract

The crystal and molecular structure of cis-bis(N-benzoyl-N′-propylthiourea) dichloroplatinum(II) shows that two N-benzoyl-N′-propylthiourea molecules co-ordinate to Pt^II through the sulfur atom only, the acyl oxygen atom being effectively blocked from co-ordination by an intramolecular hydrogen bond, in contrast to the chelating N-benzoyl-N′,N′-dialkylthiourea analogues.
