Abstract
A new Cd(II) complex, [CdL(DMSO)2Cl2] n , L = bis(N-phenylthiourea), has been synthesized and its crystal structure determined from single-crystal diffraction data. The compound is orthorhombic, space group Pna21, with a = 18.728(1), b = 12.2601(8), c = 22.879(1) Å, V = 5253.3(6) Å3. L acts as an exobidentate neutral ligand and Cd is octahedral, being bonded to two S atoms, two terminal Cl ions and two DMSO solvent molecules. The structure is that of a one-dimensional polymer, with chains running parallel to the b axis. Polymeric chains are stabilized by N–H…Cl hydrogen bonding, while intermolecular S…O contacts connect the chains. Thermal decomposition of the complex starts at 120°C by desolvation and is continuous over the recorded temperature range.Keywords
