A new cadmium(Ⅱ) coordination polymer,[Cd(Hcna)_2]_n(1),was hydrothermally synthesized based on 5-(4-carboxyphenoxy)nicotinic acid(H_2cna) organic linker.X-ray singlecrystal diffraction determination reveals that 1 crystallizes in the monoclinic P2_1/c space group,with a = 10.101(2),b = 7.9139(17),c= 15.627(3) A,β= 103.364(3)°,V= 1215.4(4) A~3,Z=2,M_r= 628.81,D_c = 1.718 Mg/m~3,μ= 0.963 mm~(-1),F(000) = 628,the final R = 0.0177 and wR = 0.0432 for 2263 observed reflections with I> 2σ(I).In 1,the Cd(Ⅱ) cations are connected by nicotiniate units to form a two-dimensional(2D) layer,and it is further linked through benzoate units to form a three-dimensional(3D) structure.Topologically,the structure of 1 represents a 3,6-connected 3D rtl topology.Furthermore,thermal stability and photoluminescent property of 1 have also been investigated.
