摘　　要：The title compound Mn 3(BTC) 2(bpy)(EG)(DMF)·(DMF)·1/3(C 2H 5OH)(BTC=1,3,5-benzenetricarboxylic acid, bpy=4,4′-bipyridine, EG=ethylene glycol, DMF=dimethylformamide) was synthesized under mild conditions and its crystal structure was determined by single crystal X-ray diffraction. The compound crystallizes in the monoclinic system and belongs to space group P2 1/n with a= 1.637 2(3) nm, b=1.481 4(3) nm, c=1.838 4(4) nm, β=113.70(3)°, V=4.082 5(14) nm 3, Z=4, D c=1.508 Mg/m 3, M r=958.85, μ=1.001 mm -1, F(000)=1 920. R 1=0.098 5, wR 2= 0.218 3. Its structure reveals that Mn(Ⅱ) centers and the carboxylate groups of BTC construct 1D O—C—O—Mn chains. Then, adjacent chains are interlinked by benzene rings of BTC to form a novel 3D architecture. It contains eight-membered rings channels that are about 0.8 nm×0.8 nm viewed along the (101) direction. In addition, it is believed that the bpy acts as both an organic ligand and a structure-directing agent in the synthesis of the title compound.The title compound Mn 3(BTC) 2(bpy)(EG)(DMF)·(DMF)·1/3(C 2H 5OH)(BTC=1,3,5-benzenetricarboxylic acid, bpy=4,4′-bipyridine, EG=ethylene glycol, DMF=dimethylformamide) was synthesized under mild conditions and its crystal structure was determined by single crystal X-ray diffraction.
