چکیده
The asymmetric unit of the title compound, C(7)H(8)N(4)S, contains two independent mol-ecules with slightly different conformations; the dihedral angles between the pyridine ring and mean plane of the thio-semicarbazone unit in the two mol-ecules are 2.88 (5) and 6.30 (5)°. Inter-molecular N-H⋯N and N-H⋯S hydrogen bonds link the mol-ecules into layers parallel to the ab plane.

In the title compound, [Cu(C(6)H(5)N(2)O)Cl(C(6)H(6)N(2)O)], the Cu atom is coordinated by one neutral and one deprotonated pyridine-2-carboxaldehyde oxime (pco) ligand, resulting in the formation of two five-membered CuN(2)C(2) rings. Together with the additional coordinating chloride anion, the coordination polyhedron of copper is best described as a distorted square-pyramid, the distortion p...

The benzene-o-dithiol/pyridylimine (S-S)/(N-N) ligand H2-7, representing the first example of a new type of bis(bidentate) heterodonor ligands with a mixed donor set, has been synthesized by Schiff base condensation of pyridine-2-carbaldehyde with an amine-substituted benzene-o-dithiol moiety. Bis(cyclopentadienyl)titanium dichloride reacts selectively at the S-S donor group of H2-7 to yield co...
