Abstract: The preparation and characterization of mixed ligand complexes of Co(II) and Fe(III) ions with malonic acid and heterocyclic amines are described here. The general formula of the complexes are; [M(MO)L] and K[M(MO)L], [whcre, M=Co(II) (1-6), Fe(II) (7-8); MO=C3H2O4 (1-6), 2 C3H2O4 (7-8); L=C6H5N (1), C5H6N2 (2), 2C9H7N (3,4,7,8), C6H6NO (5), C9H6NO (6)]. IR spectra of the complexes confirm the coordination of metal ion with ligands. The magnetic measurements indicate that the Co(II) complexes (1-6) are paramagnetic, having magnetic moment 3.91-4.21 B.M. The Co(II) complexes are assumed to have tetrahedral and the Fe(III) complexes have octahedral structure based on the electronic spectra and magnetic measurements.
