| Abstract: | The reaction of magnesium carbonate with ortho and para -aminobenzoic acid results in the formation of the complexes [Mg(H2O)6](X)2 H2O (X=2-aminobenzoate (2-aba) 1 and X=4-aminobenzoate (4-aba) 2). The 2-aminobenzoatc complex 1 has been characterised by metal analysis, isothermal weight loss studies, infrared, UV-Vis, 1H and 13C NMR spectra and x-ray powder diffraction. The 2-aba complex is relatively unstable as compared to the corresponding 4-aba analogue and slowly decomposes to [Mg(2-aba)2] with the loss of water molecules. This irreversible change is attributed to the disposition of the – NH2 group with respect to the carboxylate group in the six-membered ring. |
