Neutral copper(II) complexes with a tetradentate NNNS Schiff base have been synthesized using the ligand, di-2-pyridyl ketone N(4),N(4)-(butane-1,4-diylthiosemicarbazone (HL). A series of five binuclear complexes of HL with general stoichiometry CuLX [X= Cl (1), Br (2), NO3 (3), N-3,(4) and SCN (5)], another dinuclear complex [Cu2LCl3] (6) with copper(II) chloride, and a tetranuclear complex [Cu4L4(SO4)(2)] (7) with copper(II) sulfate were also synthesized. The crystal structure of (Cu2L2(SO4)](2) center dot 3H(2)O has been determined by X-ray diffraction studies. Crystal analysis shows that the complex is tetranuclear with five coordinated copper centers.
