A new metal-organic framework [Co3(Hbdc)2(bdc)2]· 4DMF· 2H2O (1) was synthesized through the self-assembly reaction between the mixed ligands (pyrazine, H2bdc) and transition metal ion Co2+under the solvothermal condition .Compound 1 was characterized by IR spectroscopy , TG and single-crystal X-ray diffrac-tion.The result showed that the crystal belonged to monoclinic system with C 2/c space group.The Co centers are bridged by bdc ligands with different coordination modes , generating a three-dimensional open framework , in which the crystallized DMF and water molecules are involved .
