| Abstract: A coordination polymer of {[Co(2-OPA)2(4，4′-bipy)(H2O)2]·6H2O}n (2-OPA-=2-oxo-1(4H)-pyridineacetate anion) was synthesized and characterized by elemental analysis， IR， TG， fluorescence and X-ray single crystal diffraction. The title complex crystallizes in triclinic space group P1， with a=0.856 66(17) nm， b=0.859 58(17) nm， c=1.142 2(2) nm， α=69.64(3)°， β=68.35(3)°， γ=74.88(3)°， and V=0.724 4(3) nm3， Z=1， R=0.064 4， wR=0.159 8. Each Co atom occupies a special position of inversion center and has an octahedral coordination environment， defined by two carboxyl O atoms from two 2-OPA- ligands， two N atoms from two 4，4′-bipy ligands and two water molecules. Adjacent Co(Ⅱ) atoms are bridged by 4，4′-bipy ligands， forming a one-dimensional linetype chain structure. The closest Co…Co distance is 1.142 2(2) nm. The results of TG and fluorescent analysis show that the title coordination polymer is stable under 90.2 ℃ and has three emission peaks at 368， 422 and 484 nm. CCDC: 643626. | |
