Synthesis and Characterization of Some Metal Complexes of Vitamin C. Part 2¹—Ascorbate Complexes of Mn(II), Fe(III) and Co(II)

Abstract

Previously we reported the synthesis and characterisation of vitamin C complexes of Cu(II) and Zn(II) metal ions¹. In this work, we have synthesised and characterised vitamin C metal complexes of Mn(II), Fe(III) and Co(II) by elemental analyses, magnetic moments, i.r. and u.v. spectral studies. The ascorbic acid was bidentate in its mode of complexation and binds through the carbonyl and C-2 enolic hydroxy groups. All the complexes prepared were paramagnetic and possess an octahedral structure.
