Crystal structure of [NiHg(SCN)(4)(CH(3)OH)(2)](n)

The title compound, catena-poly[[bis­(methanol-κO)nickel(II)]-di-μ-thio­cyanato-κ(4) N:S-mercurate(II)-di-μ-thio­cyanato-κ(4) N:S], was obtained from a gel-growth method using tetra­meth­oxy­silane as gelling agent. The crystal structure is composed of rather regular HgS(4) tetra­hedra (point group symmetry .2.) and trans-NiN(4)O(2) octa­hedra (point group symmetry 2..) that are linked through thio­cyanato bridges into a three-dimensional framework. The methanol mol­ecules 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.
