一维链状钴配位聚合物{[Co(4，4′-bipy)(C9H8O3N)2](H2O)4}n的溶剂热合成、晶体结构及热稳定性

One novel coordination polymer {[Co(4，4′-bipy)(C₉H₈O₃N)₂](H₂O)₄}_n with p-acetamidobenzoic acid and 4,4′-bipy has been synthesized. It was characterized as crystallizing in the triclinic space group P1, with: a=1.138 1(2) nm, b=1.165 2(2) nm, c=1.223 3(2) nm, α=88.47(3)°, β=88.00(3)°, γ=65.78(3)°, V=1.478 4(4) nm³, D_c=1.446 g·cm^-3, Z=1, F(000)=670. Final GooF=1.106, R₁=0.041 5, wR₂=0.110 4. The crystal structure shows that the cobalt(Ⅱ) ion is lined with one 4,4′-bipy molecule, forming a one-dimension chain with Z-type structure, which coordinated with two nitrogen atoms of two 4,4′-bipy molecules and four oxygen atoms from two p-acetamidobenzoic acid molecules, giving a distorted octahedral coordination geometry. The result of TG analysis shows that the title complex was stable under 230.0 ℃. CCDC: 741932.
