Synthesis and Characterization of Heterocyclic Compounds

The title compound crystallizes in a monoclinic cell with dimensions a= 12.490 (2), b= 6.024 (1), c= 10-740 (2) A and fl= 90.49 (1) °. The space group is C2/c. It has four [(SCN)2Co(H20)2]. H20 formula units in the cell. The cobalt atom lies at a symmetry centre surrounded by symmetrically related pairs of water molecules, nitrogen and sulphur atoms. Another water molecule lies on a twofold axis. The final R value is 0.03 for a total of 1091 observed Mo data. The NCS group has the normal characteristic values: N C = 1.160 (3), C-S= 1.664 (2) A and N-C-S= 179.20 (2) °. Co-N-C-S-Co links with bidentate NCS are present. The sulphur atom and the water molecules are involved in a hydrogen-bonding network.
