Synthesis of a new tris-bidentate multidentate ligand, N,N′,N″-tris[2-(N-hydroxycarbamoyl)ethyl]-1,3,5-benzenetricarboxamide (BAMTPH), designed for the binding of trivalent metal ions such as Fe(III), Ga(III), and Al(III), is described. Its cation binding affinities for hydrogen ion and for Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Ga(III), and Al(III) ions are described, and the equilibrium data are compared with those of analogous ligands. The binding constants of trivalent metal ions with the ligand do not show a chelate effect relative to the binding to individual bidentate hydroxamic acids.

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.

ME is an attractive biocatalyst for building carbon–carbon bonds through carboxylation of pyruvate with CO2. The carboxylation of pyruvate with CO2 was promoted by adding a trivalent metal ion. In particular, Al3+ accelerates ME-catalyzed carboxylation of pyruvate with CO2.
