摘　　要：A novel one-dimensional coordination polymer, {[Cd(3-CNPP)(Py)3]·2H2O}n (3-CNPP2-=2-(3-carboxymethyl-4-nitrophenyl)propionate dianion, Py=pyridine) was synthesized and characterized by the element analysis, IR, TG and single crystal X-ray diffraction. The title complex crystallizes in monoclinic system with space group P21 / n, a=0.974 81(19) nm, b=1.992 3(4) nm, c=1.459 8(3) nm, β=95.92(3)°, and V=2.820 0(10) nm3 Z=4, R=0.037 3, wR=0.083 8. Each cadmium(Ⅱ) atom is seven-coordinated by four oxygen atoms from two different 3-CNPP2- groups and three nitrogen atoms from three pyridine ligands, forming a distorted pentagonal bipyramindal coordination geometry. The cadmium(Ⅱ) atoms are bridged by the tetradentate 3-CNPP2- groups, constructing a one-dimensional zigzag chain structure along c axis. The adjacent distance of Cd...Cd atoms is 0.979 6 nm. The two-dimensional hydrogen-bonding supramolecular network was formed via the hydrogen bond interactions. CCDC: 254257.
