Bis{1-[3-(diethyl-ammonio)-propyl-imino-meth-yl]naphthalen-2-olato}nickel(II) dinitrate

(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

In the title solvated complex, [Ni(C₁₇H₂₁N₃O)(NCS)₂(CH₃OH)]·CH₃OH, the Ni²⁺ ion is coordinated by one phenolate O, one imine N, and one amine N atom of the tridentate Schiff base ligand, two thio­cyanate N atoms and one methanol O atom, resulting in a distorted cis-NiO₂N₄ octa­hedral 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.

(E)-1-(4-Chloro-benzyl-idene)thio-semi-carbazide

In the crystal of the title compound, C₈H₈ClN₃S, mol­ecules are connected by N—H⋯S hydrogen bonds into strips parallel to the (112) planes and running along [10]. One of the amino H atoms is not involved in a classical hydrogen bond. In addition, there is a rather short inter­molecular Cl⋯S distance of 3.3814 (5) Å.
