| Abstract: | Summary A series of new diamagnetic cobalt(Ill) mixed ligand complexes having general formula Co(AA)(tn)2]n+ (where AA = biguanide, picolinic acid, acetoacetanilide, benzoylacetanilide,m-nitrobenzoylacetanilide, acetylacetone,N-benzoylphenylhydroxylamine and malonic acid, tn = trimethylenediamine and n = 1–3) have been synthesized and characterized by elemental analysis, conductance measurements, electronic spectra, i.r. spectra, equivalent weight and magnetic measurements. The electronic spectra are typical of octahedral cobalt(III) complexes. The effect of cationic charge and the nature of the ligands on the Rf values of the complexes have been determined by paper chromatography.Author to whom all correspondence should be directed. |
