| 摘 要： | A novel one-dimensional coordination polymer, {Cd(PAc)2(4,4-bipy)(H2O)]·4H2O}n (HPAc=phenyl acetic acid, 4,4′-bipy=4,4′-bipyridine) was synthesized and characterized by element analysis, IR, TG and X-ray single diffraction crystal structure determination. It crystallizes in the monoclinic space group C2/c with a=2.088 5(4) nm, b=0.839 05(17) nm, c=1.683 5(3) nm, β=105.45(3)° and V=2.843 5(10) nm3, Z=4, Mr=628.94, F(000)=1 288, μ=0.820 mm-1, R=0.019 9, wR=0.056 5. Each cadmium(Ⅱ) atom is seven-coordinated by four oxygen atoms from two different phenyl acetate groups and two nitrogen atoms from two 4,4′-pyridine ligands and one water molecule, forming a distorted pentagonal bipyramid coordination geometry. Adjacent cadmium(Ⅱ) atoms are bridged by 4,4′-pyridine ligand, constructing a infinite chain along the diagonal direction of ac plane. The Cd…Cd separation within the polymer is 1.164 6(4) nm. The three-dimensional supramolecular structures of the title complexes are constructed by hydrogen bonding interactions and π-π stacking interactions between the benzene rings of HPAc and 4,4′-bipy. CCDC: 616697.
