title: Bis[tris-(1H-pyrazol-1-yl-κN)methane]-nickel(II) bis-{[tris-(1H-pyrazol-1-yl-κN)methane]-tris-(thio-cyanato-κN)nickelate(II)} methanol disolvate.
abstract: Attempts to prepare the mononuclear [(tpm)Ni(II)L(3)](-1) [tpm = tris-(1H-pyrazol-1-yl)methane and L = thio-cyanate] 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 octa-hedral nickelate(II) anion bound to one tpm and three L ligands, and a methanol solvent mol-ecule. 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 inter-actions between the methanol and the disordered thio-cyanate anion, and a weak C-H⋯O hydrogen bond between the cation and the methanol O atom.
