Synthesis and Characterization of 3-Aminomethylpyridine and the Salt of 2,6-Pyridinedicarboxylic Acid and Fe(III), Co(II) and Cu(II) Complexes of the Salt

Abstract

In this study, proton transfer salt {(H3amp)+(Hdipic)-, 1)} between 3-aminomethylpyridine (3amp) and 2,6-pyridinedicarboxylic acid (H2dipic) and it Fe(III) {(H3amp)[Fe(dipic)2].2H2O, 2}, Co(II) {(H3amp)2[Co(dipic)2].3H2O, 3} and Cu(II) {(H3amp)2[Cu(dipic)2].5H2O, 4} were synthesized. Novel compounds were characterized by FT-IR, AAS, NMR (1H and 13C), UV, magnetic, and molar conductivity tests. According to the spectroscopic analysis results, the acid:base ratio is 1:1 for salt, while the metal:acid:base ratio is 1:2:1 for 2 and 1:2:2 for 3 and 4. The structures of all complexes are proposed to be octahedral.
