Structural studies of metal complexes with NN′-disubstituted thioureas. Part I. Crystal structure of dichlorobis-(NN′-diethylthiourea)zinc( II )

The crystal structure of dichlorobis(diethylthiourea)zinc(II) has been determined and refined by anisotropic least-squares methods to R 0·082 for 4035 independent reflections. The crystals are monoclinic, space group P21/c, with Z= 8 in a unit cell of dimensions a= 10·418, b= 14·974, c= 24·078 Å, and β= 92° 16′. The structure contains two crystallographically independent molecules of different shape, which form (A) polymeric chains, (B) dimers, both by hydrogen bonding between NH groups and chlorine atoms.
