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