Synthesis and characterization of mono and binuclear cobalt [II], nicked [II] and copper [II] complexes with N2O2-schiff bases of diamino-naphthalenes

ABSTRACT

Mono and binuclear cobalt [II], nickel [II] and copper [II] complexes containing quadridentate Schiff bases were prepared and characterized by elemental analysis, 1R, electronic and epr spectra. The complexes were subjected to TGA, conductance and electrical resistivity measurements. The observed resistivities of the complexes at different temperatures follow the order Co [II]
