Synthesis and characterization of ternary carboxylato complexes of cobalt(II) with Schiff bases

2006-2010Some novel mixed-ligand, ternary carboxylato complexes of cobalt(II) with Schiff bases (HSB) having general formula [Co(OOCR)(SB)] (where R = C11H23, C13H27, C15H31 or C17H35) have been synthesized by the substitution reactions of anhydrous cobalt(II) acetate. The isolated products have been characterized by elemental analyses, molar conductance and magnetic moment measurements and spectral (infrared, electronic and FAB mass) data. Models and coordination hypotheses for the complexes have been proposed and a peculiar structural characterization has been discussed on the basis of physicochemical studies. A sharp structural change has been noticed
