摘　　要：A copper coordination polymer, {[Cu3( μ-3-CPOA)2( μ-3-PyO)2(3-PyOH)2 (H2O)4]·4H2O}n (3-CPOA2-=3-carboxylphenoxyacetate dianion, 3-PyOH=3-hydroxypyridine, 3-PyO-=pyridin-3-onato) was synthesized and char-acterized by the element analysis, IR, TG and single crystal X-ray diffraction. The title complex crystallizes in triclinic system with space group P1, a=0.906 53(18) nm, b=1.155 9(2) nm, c=1.208 0(2) nm, α=93.25(3)°, β=111.05(3)°, γ=105.62(3)° and V=1.121 0(5) nm3, Z=1, R=0.052 6, wR=0.154 8. Each copper(Ⅱ)atom displays octahedron coordination geometry incorporating 3-carboxylphenoxyacetate and pyridin-3-onato ligands, except for the Cu1 atom also involving 3-hydroxypyridine and water molecules. Two adjacent copper(Ⅱ)atoms are bridged by the tridentate 3-CPOA2- group and the tridentate pyridin-3-onato ligand, constructing a one-dimensional chain structure along b axis, with the adjacent Cu...Cu distances being 0.309 3(3) nm and 0.626 5(3) nm.
