摘　　要：Two new bearing Bi(Ⅲ) supramolecular compounds [Bi(pydcH)_(3)(Bi(pydcH)(pydcH_(2))(pydc)(Bi(pydcH)(pydcH_(2))(pydc)](1) and {[Bi(pydcH)_(3)]·(H_(2)O)_(5)(Dmap)}_(2)(2) have been successfully synthesized via hydrothermal reaction(pydcH_(2) = 2,6-pyridine dicarboxylate, Dmap = 4-dimethylamiopyridine). They have been structurally determined by single-crystal X-ray analysis, and characterized by fluorescence analysis and thermogravimetric analysis(TG). Both compounds 1 and 2 are of the same triclinic system with different structures. The decomposition mechanisms of compounds 1 and 2 are discussed. Compared to 1, lots of small molecules were possibly removed from compound 2 below 250 ℃. In addition, the photoluminescence properties were also investigated.
