Abstract:

Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) complexes of the type [ML2(NO3)2] and [PdL2]Cl2, where L is the Schiff base {2-(3-iodo-4-methyl-phenylimino)-2H-napthalene-1-one} formed by condensation of 1,2-napthadione and 3-iodo-4-methylaniline, have been prepared and characterized by elemental analysis, molar conductance, magnetic susceptibility, infrared and electronic spectral measurements. Elemental analysis suggests the stoichiometry to be 1:2 (metal : ligand). Magnetic data coupled with electronic spectra corroborate a six coordinate octahedral structure for all the complexes, with exception of [PdL2]Cl2 which adopts a 4-coordinate square-planar geometry. Infrared data indicate coordination of the central metal atom through the imine N, keto O and nitrate N atoms. They are all magnetically dilute and non-electrolyte in DMF with exception of [PdL2]Cl2 which is a 1:2 electrolyte.
