catena-Poly[[bis­(pyridine-κN)nickel(II)]-di-μ-thio­cyanato-κ²N:S;κ²S:N]

In the title compound, [Ni(NCS)₂(C₅H₅N)₂]_n, the Ni²⁺ cation is coordinated by four thio­cyanate anions (μ-1,3) and two pyridine ligands within a slightly distorted octa­hedral configuration. The Ni—N bond lengths to the pyridine rings are 2.1189 (17) and 2.1241 (17) Å, whereas those to the thiocyanate anions are 2.0299 (18) and 2.0359 Å. The Ni—S bond lengths are 2.5357 (6) and 2.5568 (6) Å. The Ni²⁺ cations are linked by N:S-bridging thio­cyanate ligands into chains extending along [010]. The Ni...Ni distance within the chains is 5.5820 (5) Å. The asymmetric unit contains two Ni²⁺ cations of which one is located on a centre of inversion, whereas the second is located on a general position.
