STUDIES OF NICKEL(II) COMPLEXES OF 3-HYDROXYIMINOBUTANONE THIOSEMICARBAZONE AND 3-HYDROXYIMINOBUTANONE (4-PHENYL THIOSEMICARBAZONE) - CRYSTAL STRUCTURE OF BIS(3-HYDROXYIMINOBUTANONE) (4-PHENYL THIOSEMICARBAZONE) NICKEL(II) NITRATE, MONOHYDRATE, [NI(C

摘要

Nickel(II) complexes of two tridentate N.N.S-chelating ligands, 3-hydroxyimino-butanonethiosemicarbazone (L(1)H(2)) and 3-hydroxyiminobutanone (4-phenylthiosemicarbazone) (LH(2)), have been synthesized and characterized by elemental analysis, IR, UV-vis spectroscopy and cyclic voltammetric studies. The structure of Ni(LH(2))(2)(NO3)(2) . H2O has been determined by single-crystal X-ray diffraction. Nickel(II) is in a distorted octahedral N4S2 donor environment; one of the nitrate groups exhibits partial disorder. (C) 1997 Elsevier Science Ltd. [References: 35]
