| Summary: | In the title compound, [Zn(NCS)(C16H18N4)]ClO4, the ZnII atom is five-coordinated by four N atoms of the Schiff base ligand N,N′-bis[1-(2-pyridyl)ethylidene]ethane-1,2-diamine in the basal plane, and by the N atom of a thiocyanate ligand at the apical position, forming a distorted square-pyramidal geometry. The r.m.s. deviation from a plane through the four N atoms of the Schiff base is 0.015 (3) Å, and the deviation of the Ni atom from that plane is 0.591 (2) Å. Bond lengths are comparable with those observed in similar zinc(II) complexes with Schiff bases. The two methylene C atoms of the ethane-1,2-diamine bridge of the Schiff base ligand are disordered over two sites with occupancies of 0.587 (3) and 0.413 (3).
