catena-Poly[bis­[cis-dipyrimidine-trans-dithio­cyanato­iron(II)]-di-μ-pyrimidine-[trans-dithio­cyanato­iron(II)]-di-μ-pyrimidine]

In the crystal structure of the title compound, [Fe(3)(NCS)(6)(C(4)H(4)N(2))(8)](n), each iron(II) cation is coordinated by four N-bonded pyrimidine ligands and two N-bonded thio­cyanate anions in a distorted octa­hedral environment. The asymmetric unit consists of one iron cation located on a crystallographic center of inversion, as well as one iron cation, three thio­cyanate anions and four pyrimidine ligands occupying general positions. The structure consists of square secondary building units (SBUs) with an Fe atom at each corner, which are μ-N (1):N (3)-bridged by the pyrimidine ligands. The SBUs are linked into infinite chains running in the c-axis direction via common opposite corners.
