The different complexation methods of a proton transfer compound, (phenH)2(pydc) (phen=1,10-phenanthroline; pydcH2= pyridine-2,6-dicarboxylic acid), are discussed and the formation of [Sn(pydc)(phen)(OH)2].3H2O (1), {[Sb(pydc)(phen)]2O}.2DMSO.4H2O(2) and [(Tl(pydcH)]n (3) complexes are reported. The characterization was performed using IR spectroscopy and X-ray diffraction. The structures of Sn(IV) and Sb(III) complexes show that both cationic and anionic fragments of the starting proton transfer compound have been involved in the complexation. Whereas the structure of Tl(I) complex demonstrates that only the anionic fragment of (phenH)2(pydc) is contributed to the complexation. The complexes 1-3 show a variety of structural features including mononuclear, binuclear and polymeric structures. In compounds (1), (2) and (3) a large number of hydrogen bonds are observed. These interactions play an important role in the formation and stabilization of supramolecular systems in the crystal lattices.
