Synthesis of iron(III), cobalt(II), nickel(II), copper(II) and zinc(II) complexes with new quadridentate N,O-donor ligands

摘要

The reaction between anthranilic acid and oxalyl chloride/malonyl chloride results in new quadridentate ligands, bis(2-carboxyphenyl)oxamide [CPOA]/bis(2-carboxyphenyl)malonamide [CPMA]. These ligands form 1: 1 complexes of general formula, [Fe(L)(H_2O)_2]Cl, [M(L)] and [Zn(L)].2H_2O, where L = CPOA or CPMA, M = Co~II, Ni~II, or Cu~II.
