Anion directed cation templated synthesis of three ternary copper(II) complexes with a monocondensed N2O donor Schiff base and different pseudohalides

A tridentate monocondensed N2O donor Schiff base ligand has been trapped in three different copper(II) complexes. X-ray diffraction studies have confirmed the structures of the complexes. The formation of the complexes have been explained by the concept of anion directed cation templated synthesis. Variable temperature magnetic measurements indicate antiferromagnetic interactions between the copper(II) centers in all three complexes.
