摘      要：Two new d;metal-based metal-organic frameworks,{[Zn;（btc）;（bib）;（H;O）;]·2H;O};（1）and{[Cd;（btc）;（bib）;（H;O）;]·6H;O};（2）(btc=1,3,5-benzenetricarboxylate anion,bib=1,4-bis（1-imidazolyl）benzene)have been prepared under hydrothermal conditions by the reactions of d;metal oxides of ZnO and CdO with the aromatic polycarboxylic H;btc and the N-heterocyclic bib.The two products were characterized by single-crystal X-ray diffraction analysis,elemental analysis,thermogravimetric analysis（TGA）,and IR spectroscopy.Complexes 1 and 2 crystallize in monoclinic C2/c and triclinic P 1 space groups,respectively.1 shows a 3D framework,and the potential large voids of the 3D network lead to a 3-fold interpenetrating architecture.2 displays a 2D framework,and the adjacent 2D layers expand into a 3D supramulecular network via rich hydrogen bonds.Moreover,the luminescent properties of the two complexes are investigated in solid state.
