Complexes of Oxamic Acid with Al(III), Ga(III), In(III), Tl(III), Y(III), Fe(III), Mn(II) and V(III)
View through CrossRef
The preparation of complexes of oxamic acid with Al(III), Ga(III), In(III), Tl(III), Y(III), Fe(III), Mn(II) and V(III) is reported. From the study of the infrared and diffuse reflectance spectra and the magnetic moments (for the complexes of Fe(III), Mn(II) and V(III)) it is concluded that in all complexes the metal ion is coordinated with the carboxyl oxygen and the amidic nitrogen, after the ionization of one of the amidic hydrogens.
Octahedral structures are proposed for all the complexes of the trivalent metal ions and the complex K2{Mn(oxamic)2} · 2 H2O.
