The title complexes, [Ni(C11H14ClN2O)(NCS)], (I), and [Ni(C11H14ClN2O)(N-3)](n), (II), are two different structures constructed from the same Schiff base ligand, viz. 4-chloro-2[ 2-(dimethylamino) ethyliminomethyl] phenol, and different linear triatomic secondary ligands, viz. thiocyanate for ( I) and azide for ( II). In mononuclear ( I), the Ni-II atom is four-coordinated in a square-planar geometry by the N, N', O-donor set of the Schiff base and by the N atom of the terminal thiocyanate ligand, while in polynuclear ( II), the Ni-II atom is five-coordinated in a square-pyramidal geometry by the N, N', O-donor set of the Schiff base and by two N atoms from two bridging azide groups.
