{S-Benzyl 3-[(6-methyl-pyridin-2-yl)-methyl-idene]dithio-carbazato}nickel(II) monohydrate.

The structure of the title compound, [Ni(C(15)H(14)N(3)S(2))(2)]·H(2)O, has one mol-ecule in the asymmetric unit, along with a solvent water mol-ecule. The two different Schiff base moieties coordinate to the central Ni(II) ion as tridentate N,N',S-chelating ligands, creating a six-coordinate distorted octa-hedral environment [the smallest angle being 77.43†(7)° and the widest angle being 169.99†(7)°]. The mean planes of the two ligands are nearly orthogonal to each other with an angle of 89.53†(6)°. The packing of the complex is supported by O-H⋯N and O-H⋯S hydrogen bonding between the solvent water mol-ecule and the uncoordinated N and S atoms of neighbouring ligands.
