英文摘要：

A three-dimensional supramolecular compound[CO（bppdca）2（HL）2（H2O）2]·2H2O][bppdca= N,N′-bis（pyridine-3-yl）pyridine-3,5-dicarboxamide,L = trans-1,4-cyclo-hexanedicarboxylic acid]has been hydrothermally synthesized and structurally characterized by elementary analysis,IR and single crystal X-ray diffraction analysis.The compound crystallizes in monoclinic system,space group P21/n,a=0.820 65（6）nm,b=1.259 76（9）nm,c=2.479 11（18）nm,β=98.061 0（10）°,Z=2,V=2.537 6（3）nm3,Mr=1 111.98,Dc=1.455g/cm3,F（000）=116 2,μ=0.421 mm-1,S=1.018,R=0.041 7,wR=0.102 3.The crystal structure analysis indicates that the CoⅡ cation coordinates with two bppdca ligands,two HL anions and two coordinated water molecules to form single metallic complex.The adjacent complexes are linked by hydrogen bonding interactions to form a three dimensional supramolecular framework.Moreover,the thermal stability,photoluminescent property and photocatalytic activity of the title compound were investigated.
