title: (Methanol-κO){1-[2-(piperazin-4-ium-1-yl-κN(1))ethyl-imino-methyl-κN]naphthalen-2-olato-κO}bis-(thio-cyanato-κN)nickel(II) methanol monosolvate.
abstract: In the title solvated complex, [Ni(C(17)H(21)N(3)O)(NCS)(2)(CH(3)OH)]·CH(3)OH, the Ni(2+) ion is coordinated by one phenolate O, one imine N, and one amine N atom of the tridentate Schiff base ligand, two thio-cyanate N atoms and one methanol O atom, resulting in a distorted cis-NiO(2)N(4) octa-hedral geometry. The chelate ring formed by the phenolate O and imine N atoms approximates to an envelope with the Ni atom as the flap, whereas the chelate ring formed by the two N atoms is twisted about the C-C bond. In the crystal, the components are linked by O-H⋯O, N-H⋯O, N-H⋯S, and O-H⋯S hydrogen bonds.
