Solid-Liquid Reaction Synthesis and Characterization of Bioinorganic Complexes of Nicotinic Acid with Antimony(III) and Bismuth(III) Ion

摘要

Bioinorganic complexes of nicotinic acid with trivalent antimony and bismuth are synthesized by solid-liquid reaction at room temperature. The formula of the complexes is Sb(C_5H_4NCOOH)_2Cl_3·H_2O and Bi(C_5H_4NCOOH)_2Cl_3·H_2O respectively. The crystal structure of the complex of nicotinic acid and Sb(III) belongs to triclinic system and that of nicotinic acid and Bi(III) belongs to monoclinic system. Thermal analysis can indicate the complex formation between antimony or bismuth ion and nicotinic acid.
