Attempts to prepare the mononuclear [(tpm)NiII L 3]-1 [tpm = tris-(1H-pyrazol-1-yl)methane and L = thio-cyanate] anion yielded the methanol-solvated salt, [(tpm) 2NiII][(tpm)NiII(NCS)3] 2·2CH3OH or [Ni(C10H10N 6)2][Ni(NCS)3(C10H 10N6)]2·2CH3OH. 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 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 thio-cyanate anion, and a weak C-H⋯O hydrogen bond between the cation and the methanol O atom.
