catena-Poly[[bis-(thio-cyanato-κN)iron(II)]-bis-(μ-dipyrazin-2-yl di-sulfide-κ(2) N (4):N (4'))]

In the title compound, [Fe(NCS)2(C8H6N4S2)2] n , the Fe(II) cation is coordinated by two terminal N-bonded thio-cyanate anions and four bridging N:N'-bridging dipyrazin-2-yl di-sulfide ligands in an octa-hedral geometry. The Fe(II) cations are connected via bridging 4,4'-di-pyrazine ligands into chains along the b-axis direction. The asymmetric unit consists of one Fe(II) cation located on position with site symmetry 2/m, one thio-cyanate anion located on a mirror plane and one di-sulfide ligand located on a twofold rotation axis.
