The construction ,crystal structure and properties and potential application of metal imidazoledi-carboxylate frameworks have currently attracted considerable attention .A novel open-framework Lantha-nideimidazoledicarboxylate ,[Tb(HpyimdC)(C2O4)0.5(H2O)]·(H2O)3(compound1),hasbeencon-structed from 2-(pyridine-3-yl)-1H-4 ,5-imidazoledicarboxylate (H3 PyImdc) and Oxalate coordinated with rare earth metal under solvothermal conditions .Single-crystal X-ray diffraction analysis reveals that com-pound 1 crystallized in the monoclinic space group C2/c (No .15) .Oxalate chelated with Tb to form a one-dimensional zigzag chain , H3 pyimdc with selective nitrogen-oxygen chelating site ,and these chains has been constructed into metal organic frameworks featuring extra-large channels deposited by guest mole-cules .
