Abstract

The asymmetric unit of the title compound, [Zn(NCSe)2(C4H4N2)2], consists of one ZnII cation, located on a twofold rotation axis, one selenocyanate anion and one pyridazine ligand in general positions. The ZnII atom is coordinated by two N-atoms of two pyridazine ligands and two terminal N-bonded selenocyanate anions within a slightly distorted tetrahedral coordination environment. In the crystal, discrete complex molecules are arranged in layers parallel to the ac plane, with ZnII⋯ZnII distances of 8.0906 (6) Å along the a axis and of 9.0490 (7) or 9.3604 (7) Å along the c axis. The complex molecules are further linked via weak Se⋯Se interactions, with Se⋯Se distances of 3.8235 (9) Å.
