摘　　要：In this paper,a Cd(Ⅱ)metal-organic framework(MOF),Cd-DIBT(HDIBT=5-(3?,5?-di(1 Himidazol-1-yl)-[1,1?-biphenyl]-4-yl)-1 H-tetrazole),has been constructed based on a newly designed heterotopic tripodal ligand containing both imidazolyl and pyrazolyl groups.The Cd-DIBT exhibits a new three-dimensional(3,3,9)-connected trinodal network topology with point symbol of(42·6)(43)2(48·615·812·10)(namely scnu)based on binuclear secondary building blocks(SBUs).Staggered 1 D channels were observed in such framework and was estimated to have 5487?^(3)potential solvent area(56%).The stability study reveals that the framework is unstable and easily transforms into amorphous MOF after the removal of guest molecules.In addition,the Cd-DIBT shows a ligand-centered luminescence.
