title: Bis(pyridazine-κN)bis-(seleno-cyanato-κN)zinc.
abstract: The asymmetric unit of the title compound, [Zn(NCSe)(2)(C(4)H(4)N(2))(2)], consists of one Zn(II) cation, located on a twofold rotation axis, one seleno-cyanate anion and one pyridazine ligand in general positions. The Zn(II) atom is coordinated by two N-atoms of two pyridazine ligands and two terminal N-bonded seleno-cyanate anions within a slightly distorted tetra-hedral coordination environment. In the crystal, discrete complex mol-ecules are arranged in layers parallel to the ac plane, with Zn(II)⋯Zn(II) 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 mol-ecules are further linked via weak Se⋯Se inter-actions, with Se⋯Se distances of 3.8235 (9) Å.
