Synthesis and Characterization of Bismuth(III) Complexes with Pyridinecarboxylic Acid

Two new bismuth(Ⅲ) complexes with pyridinecarboxylic acid,[Bi(C5H4NCOO)3]〗·H2O(1),BiCl3〗·(C5H4N-COOH)〗·1.5H2O(2),were synthesized by the solid-liquid phase or solid-solid phase.The complexes were characterized by elemental analysis,FT-IR,X-ray powder diffraction and DTA.Both the complexes belong to monoclinic,and the lattice parameters are a=2.0999nm,b=0.9499 nm,c=1.1815 nm,β=104.999° for [Bi(C5H4NCOO)3]〗·H2O;a=1.8589nm,b=1.6889nm,c=1.2049 nm,β= 96.445° for BiCl3〗·(C5H4NCOOH)〗·1.5H2O.Some influence on structure and character were carried out.
