Bis(pyridazine-?N)bis-(seleno-cyanato-?N)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.
