One cadmium coordination polymer with 2-Fold parallel Interpenetration Structure and Helical Chains based on biphenyl-4-hydroxyl-3,3'-bicarboxylic acid (H2L) and mu-4,4'-bipyridine (bpy) {[Cd(L) (bpy)(1/2)(H2O)](2)}(n) (1), has been obtained by hydrothermal synthesis and characterized by elemental analysis, powder X-ray diffraction (PXRD), IR spectra, thermal gravimetric analyses (TGA) and also by single-crystal X-ray diffraction. It crystallizes in the monoclinic, space group P2(1)/c. The L2- anions of complex 1, as a bridging ligand, connect Cd(II) ions to form two-dimensional (Cd-2(L)(2))(n) layer in which the 1D (Cd-L)(n) helical chains are alternately arranged in a right- and left-handed sequence. These layers are further linked to build a three-dimensional network by the bpy ligands. In addition, the photochemical property of compound 1 has also been investigated.
