A new amide ligand, N,N'-bis(2-carboxylphenyl)-2,6-pyridinedicarboxamide (BCPD), formed by the condensation of 2,6-pyridine dicarbonyldichloride with 2-aminobenzoic acid has been structurally characterized. Binuclear Cu(II), Co(II), Ni(II), Mn(II), Zn(II) and Cd(II) complexes have been synthesized for the first time. Their structures have been elucidated on the basis of elemental analyses, conductance measurement, magnetic moment, spectral (IR,NMR,UV-Vis, EPR and FAB) and thermal studies. Infrared spectra of the complexes indicate the participation of uncharged amide oxygen atoms, pyridine nitrogen and carboxylic acid groups in a chelating bidentate fashion via deprotonation. The studies reveal that both the metal ions are present in an octahedral environment. Non-electrolytic nature of the complexes is evidenced by their low conductance data. X-band EPR spectra of the binuclear Cu(II) and Mn(II) complexes in polycrystalline state at room temperature and liquid nitrogen temperature were recorded and their salient features are reported. Thermal stabilities of the Zn(II) and Cd(II) complexes have been studied.
