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.
