title: [1-(5-Bromo-2-oxidobenzyl-idene)thio-semicarbazidato-κ(3)O,N(1),S](pyridine-κN)nickel(II).
abstract: The reaction of 5-bromo-salicyl-aldehyde thio-semicarbazone with nickel acetate tetra-hydrate and pyridine yielded the title compound, [Ni(C(8)H(6)BrN(3)OS)(C(5)H(5)N)]. The Ni(II) atom is four-coordinated in a square-planar environment by one deprotonated dianionic thio-semicarbazone ligand, acting in a tridentate chelating mode through N, O and S atoms forming two metalla-rings, and by one pyridine mol-ecule. The complex mol-ecules are linked into dimers by pairs of centrosym-metrical N-H⋯N inter-actions. In addition, mol-ecules are connected through inter-molecular Br⋯Br inter-actions [3.545 (1) Å], forming chains along the b-axis direction.
