A three-dimensional coordination polymer {[Cd2(HCAM)2(H2O)4]·3.5H2O}n was synthesized by the hydrothermal reaction of H3CAM (H3CAM = 4-hydroxypyridine-2,6-dicerboxylic acid) and Cd(NO3)2·4H2O.The structure was characterized by elemental analysis,thermal gravimetric analysis,infrared spectroscopy and single-crystal X-ray diffraction.It crystallizes in triclinic,space group P-1 with a = 9.4389(19),b = 11.009(2),c = 11.192(2) (A),α = 87.87(3),β =74.63(3),y = 81.22(3)°,V= 1108.2(4) (A)3,Z= 2,Dc= 2.164 g/cm3,μ = 2.011 mm-1,F(000) = 710,R= 0.0419 and wR = 0.1170.X-ray analysis reveals that the title compound adopts a one-dimensional staircase structure by carboxyl of H3CAM and water molecules,and it is further linked by hydrogen bonds to form a 3-D metal-organic open framework.The thermal gravimetric analysis displays that the framework exists stably below 300 ℃.
