Intramolecular hydrogen-bond-directed coordination: trans-bis(N-benzoyl-N′-propylthiourea-κS)diiodoplatinum(II) and trans-bis(N-benzoyl-N′-propylthiourea-κS)dibromoplatinum(II)
Abstract
In the title compounds, trans-[PtI2(C11H14N2OS)2], (I), and trans-[PtBr2(C11H14N2OS)2], (II), respectively, intramolecular N—H⋯O (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—H⋯X (X is I or Br) interactions (benzoylamine side) lead to slight distortions of the PtII coordination spheres from ideal square-planar geometry. The PtII ion is located on an inversion centre in both structures.
