A novel terbium(III)coordination polymer[Tb(2,4-D)3(2,2′-bipy)]n(1)(2,4-D=2,4-dichlorophenoxyacetic acid,2, 2′-bipy=bipyridine) was prepared under hydrothermal condition,and characterized by single crystal X-ray diffraction technique,IR and fluorescence spectrum. Structural analysis discovered that complex1crystallizes in the monoclinic crystal system,P2(1)/n space group with crystal cell parameters:a=2. 792(1)nm,b=0. 851(3)nm,c=3. 335(1)nm,β=113. 6470(1)°,V=7. 2575(5)nm3,Z=4. The Tb3+ ion of 1is in a eight-coordinated distorted anti-square prism geometry. Complex1exhibits one-dimension triplet helix chain structure from the Tb3+ ions bridged by the carboxyl groups of 2,4-D ligands. Fluorescence analysis showed that 1 could be potential green luminescent material.
