Abstract: In the crystal structure of the title compound, [Fe₃(NCS)₆(C₄H₄N₂)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 -N¹:N³-bridged by the pyrimidine ligands. The SBUs are linked into infinite chains running in the c-axis direction via common opposite corners.
