The asymmetric unit of the title compound, [Zn(NCSe)2(C4H4N2)2]n, consists of one Zn2+ cation located on a special position with site symmetry 2/m, one selenocyanate anion on a mirror plane and one pyrimidine ligand on a twofold rotation axis. The zinc cation is coordinated by six N atoms of four pyrimidine ligands and two N-bonded selenocyanate anions in mutually trans orientations within a slightly distorted octahedral coordination environment. The Zn atoms are μ-1,3-bridged via the pyrimidine ligands into a polymeric layer extending parallel to (100).
