Hydrothermal Synthesis, Crystal Structure and Fluorescence Propetty of a Novel Coordination Polymer[Eu2（C6H8O4）3（H2O）2]n·n（4,4＇-bpy）

A novel coordination polymer [Eu2(C6H8O4)3(H2O)2]n·n(4,4'-bpy) was synthesized by the hydrothermal reaction of EuCl3·6H2O, adipic acid and 4,4'-bpy, and its structure was determined by elemental analysis, IR, TGAGTA, single-crystal X-ray diffraction and fluorescence property. The threedimensional network has been formed between Eu3+ by carboxyl of adipic acid.
