Abstract

In our series of investigations into the structural and thermal behaviour of metal thiourea (tu) complexes, the single-crystal X-ray structure of dichlorobis(thiourea-S)-zinc(II) is redetermined at higher accuracy to R = 0.0315 proving the space group Pnma. Half of the complex molecule is in the asymmetric unit, the Zn and the two Cl atoms lie on the mirror plane. The structure analysis shows tetrahedral coordination of the Zn cation, the coordination sphere of the chloride anions and the extended hydrogen bond network. A chloride ligand is situated in the middle of the sandwich formed by bilayers of the complex molecules. We previously characterized the Cd analogue, allowing a structural comparison between the non-isostructural complexes: Mtu2Cl2 (M = Zn, Cd). Also the thermal properties of the complexes and their behaviour in chemical spray pyrolysis (CSP) processes are briefly correlated with the structure and bonding.
