title: Crystal structure of [NiHg(SCN)4(CH3OH)2] n.
abstract: The title compound, catena-poly[[bis-(methanol-κO)nickel(II)]-di-μ-thio-cyanato-κ(4) N:S-mercurate(II)-di-μ-thio-cyanato-κ(4) N:S], was obtained from a gel-growth method using tetra-meth-oxy-silane as gelling agent. The crystal structure is composed of rather regular HgS4 tetra-hedra (point group symmetry .2.) and trans-NiN4O2 octa-hedra (point group symmetry 2..) that are linked through thio-cyanato bridges into a three-dimensional framework. The methanol mol-ecules coordinate via the O atom to the Ni(2+) cations and point into the voids of this arrangement while a weak O-H⋯S hydrogen bond to an adjacent S atom stabilizes it.
