| Abstract: | A novel metal-organic coordination polymer, Cd(HPT)2(4,4′-bpy)]n (PT=phthalate), has been hydrothermally synthesized and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. Colorless crystals crystallized in the tetragonal system, space group I4122, a=8.294(5), b=8.294(5), c=33.7535(17) Å, V=2321.8(18) Å3, Z=4 and R=0.0207. The structure of the compound exhibiting a homochiral 3D covalent framework based on achiral bridging ligands has been constructed by an alternating assembly of vertical chiral layers consisting of homochiral helices. |
