Bis[tris­(1H-pyrazol-1-yl-κN (2))methane]­nickel(II) bis­{[tris­(1H-pyrazol-1-yl-κN (2))methane]­tris­(thio­cyanato-κN)nickelate(II)} methanol disolvate

Attempts to prepare the mononuclear [(tpm)Ni(II) L (3)](−1) [tpm = tris­(1H-pyrazol-1-yl)methane and L = thio­cyanate] anion yielded the methanol-solvated salt, [(tpm)(2)Ni(II)][(tpm)Ni(II)(NCS)(3)](2)·2CH(3)OH or [Ni(C(10)H(10)N(6))(2)][Ni(NCS)(3)(C(10)H(10)N(6))](2)·2CH(3)OH. The asymmetric unit consists of half a centrosymmetric bis­[tris­(1H-pyrazol-1-yl)methane]­nickel(II) cation and an octa­hedral nickelate(II) anion bound to one tpm and three L ligands, and a methanol solvent mol­ecule. One of the L ligands is disordered over two positions with occupancy factors of 0.650 (3) and 0.350 (3). There are O—H⋯S inter­actions between the methanol and the disordered thio­cyanate anion, and a weak C—H⋯O hydrogen bond between the cation and the methanol O atom.
