A one-dimensional zigzag chain complex of Cd(FA)(pyim)(H_2O)(1)(H_2FA=4,4’-(hexafluoroisopropylidene)bis(benzoic acid)and pyim=2-(2-pyridyl)imidazole)was hydrothermal synthesized from Cd(NO_3)_2·4H_2O,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 hydrogenbonds and π…πstacking interactions.The crystal is of monoclinic,space group P2_1/n with a=O.856 34(10)nm,b=1.02049(12)nm,c=2.8090(3)nm,β=98.115(2)°,V=2.4302(5)nm~3,D_c=1.820 g·cm~(-3),Z=4,F(000)=1320,Goof=1.009,R_1=0.047 0,wR_2=0.115 5.In addition,complex 1 exhibits strong photohminescent emission at room temperature.
