Bis[?(2)-1-(2-carb-oxy-benzo-yl)thio-semi-carbazide(3-)]hexa-pyridine-trinickel(II) pyridine monosolvate monohydrate.

ABSTRACT: The reaction of Ni(OAc)(2)·4H(2)O with 1-(2-carb-oxy-benzo-yl)thio-semicarbazide (H(3)L) produces the title complex, [Ni(3)(C(9)H(6)N(3)O(3)S)(2)(C(5)H(5)N)(6)]·C(5)H(5)N·2H(2)O, which contains an linear array of three Ni(II) atoms. The asymmetric unit contains half of the complex mol-ecule, a water mol-ecule and a half-mol-ecule of pyridine. The central Ni(II) atom, located on a crystallographic inversion centre, has an octa-hedral N(4)O(2) environment. The other two Ni(II) atoms have a square-pyramidal N(3)OS environment, each bridged to the central Ni(II) atom via the L(3-) group. The carboxyl-ate groups coordinate to the metal atoms in a monodentate fashion. The water mol-ecule is linked to the complex mol-ecule via O-H?O hydrogen bonds. The mol-ecules further assemble into a one-dimensional network parallel to [001] via inter-molecular N-H?O hydrogen bonds.
