Intramolecular hydrogen-bond-directed coordination: trans-bis(N-benzoyl-N'-propylthiourea-S)diiodoplatinum(II) and trans-bis(N-benzoyl-N'-propylthiourea-S)dibromoplatinum(II)

Abstract: In the title compounds, trans-[PtI₂(C₁₁H₁₄N₂OS)₂], (I), and trans-[PtBr₂(C₁₁H₁₄N₂OS)₂], (II), respectively, intramolecular N-HO (propylamine side) hydrogen bonds in the potentially bidentate thiourea ligands lock the carbonyl O atoms into six-membered rings, determining the S-monodentate mode of coordination of these ligands. Intramolecular N-HX (X is I or Br) interactions (benzoylamine side) lead to slight distortions of the Pt^II coordination spheres from ideal square-planar geometry. The Pt^II ion is located on an inversion centre in both structures.

Formula: [PtI₂(C₁₁H₁₄N₂OS)₂] and [PtBr₂(C₁₁H₁₄N₂OS)₂]
