Abstract
A series of copper(II) complexes ligated by 2,3-Dimethyl-4-formyl-[2′-(aminomethyl)pyridine]-1-phenyl-3-pyrazolin-5-one (DFAPP), [Cu(DFAPP)2Cl2](1), [Cu(DFAPP)2Br2](2),[Cu(DFAPP)2](NO3)2(3) and [Cu(DFAPP)2](ClO4)2(4) has been synthesized and characterized with the help of elemental analysis, molar conductance magnetic moments and IR, UV and EPR spectroscopic data. The Schiff base is found to act as bidentate ligand using NO donor set of atoms leading to an octahedral geometry around central metal ion in the complexes 1 and 2 and a square planar geometry in 3 and 4.
