摘　　要：A one-dimensional zigzag chain complex of Cd(FA)(pyim)(H2O) (1) (H2FA=4,4′-(hexafluoroisopropylidene)bis(benzoic acid) and pyim=2-(2-pyridyl)imidazole) was hydrothermal synthesized from Cd(NO3)2·4H2O, 4,4′- (hexafluoroisopropylidene)bis (benzoic acid) and 2-(2-pyridyl)imidazole. Single-crystal X-ray analysis revealed that the zigzag chains of 1 are linked into three-dimensional supramolecular networks by both O-H …O hydrogen- bonds and π…π stacking interactions. The crystal is of monoclinic, space group P21/n with a=0.856 34(10) nm, b=1.020 49(12) nm, c=2.809 0(3) nm, β=98.115(2)°, V=2.430 2(5) nm3, Dc=1.820 g·cm-3, Z=4, F(000)=1 320, Goof= 1.009, R1 =0.047 0, wR2 =0.115 5. In addition, complex 1 exhibits strong photoluminescent emission at room temperature.

Single-erystal X-ray analysis revealed that the zigzag chains of 1 are linked into three-dimensional supramoleeular networks by both O-H…O hydrogen-bonds and π…π stacking interactions. The crystal is of monoelinie, space group P21/n with a=0.85634（10） nm, b= 1.02049（12） nm, c=2.8090（3）nm, β=98.115（2）°, V=2.4302（5） nm^3, Dc= 1.820g·cm^-3, Z=4, F（000）= 1320, Goof= 1.009, R1=0.0470, ωR2=0.1155. In addition, complex 1 exhibits strong photolumineseent emission at room temperature.
