摘　　要：A new 3-D two-fold interpenetrated coordination polymer [Cd(SDC)(H2O)] has been synthesized by using the trans-4,4′-stilbenedicarboxylic acid(H2SDC) and Cd(NO3)2·6H2O under hydrothermal conditions,and characterized.Single-crystal X-ray structural analysis indicates that the title compound crystallizes in a monoclinic lattice,P2/c with a=15.158(2),b=6.4390(15),c=7.1330(19),β= 91.937(2)°,Z=1,V= 695.8(3)3,Dc=1.888 Mg·m-3,F(000)=390,R1=0.0476,wR2=0.0935.The title compound has an interpenetrated(4,4) topology in which central Cd(II) has greatly distorted hexahedral geometry.There are two distinct double-strand helicates,and interpenetrated rhombic nanochannels in the 3-D open framework.Compound 1 exhibits expected strong luminescence at λmax=460 nm upon excitation at 392 nm.A new 3-D two-fold interpenetrated coordination polymer [ Cd（SDC） （H2O） ] has been synthesized by using the trans-4,4＇- stilbenedicarboxylic acid （H2SDC） and Cd（ NO3 ）2· 6H2O under hydrothermal conditions, and characterized. Single-crystal X-ray structural analysis indicates that the title compound crystallizes in a monoclinic lattice, P2/c with a = 15. 158（ 2 ）, b = 6. 4390（ 15 ）, c=7.1330（19）A, β= 91.937（2）°,Z=1,V= 695.8（3）A^3,Dc=1.888 Mg· m^-3, F（000） =390, RI =0.0476, wR2=0.0935. The title compound has an interpenetrated （4,4） topology in which central Cd （Ⅱ） has greatly distorted hexahedral geometry. There are two distinct double-strand helicates, and interpenetrated rhombic nanochannels in the 3-D open framework. Compound 1 exhibits expected strong luminescence at λmax =460 nm upon excitation at 392 nm.
