Designed synthesis of copper(II) and nickel(II) complexes with a tridentate N2O donor Schiff base: Modulation of crystalline architectures through CH⋯π and anion⋯π interactions

Two copper(II) and two nickel(II) complexes have been prepared using a tridentate N2O donor Schiff base. All four complexes are mononuclear with the central metal ions assuming square planner geometries. The Schiff base is so designed that no H-bonding interactions are present in all the complexes. CH⋯π and anion⋯π interactions modulate the crystalline architectures of the complexes.
