Two different structures controlled by small secondary ligands: {4-chloro-2-[2-(dimethylamino)ethyliminomethyl]phenolato}thiocyanatonickel(II) and catena-poly[[{4-chloro-2-[2-(dimethylamino)ethyliminomethyl]phenolato}nickel(II)]--azido]

Abstract: The title complexes, [Ni(C₁₁H₁₄ClN₂O)(NCS)], (I), and [Ni(C₁₁H₁₄ClN₂O)(N₃)]_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.

Formula: [Ni(C₁₁H₁₄ClN₂O)(NCS)] and [Ni(C₁₁H₁₄ClN₂O)(N₃)]
