英文摘要	Four new complexes have been synthesized by solvothermal reactions of an imidazole-containing ligand 3,3′,5,5′-tetraĲ1H-imidazol-1-yl)-1,1′-biphenyl (L) with corresponding metal salts via the alternation of auxiliary multicarboxylates, [Zn2ĲL)Ĳ2,6-NDC)ĲOAc)2]·2H2O (1), [Zn2ĲL)ĲBPnDC)2]·6H2O (2), [Co2ĲL)ĲOBA)2]·8H2O (3) and [Zn4ĲL)2ĲODAC)2]·2MeCN·5H2O (4) (2,6-H2NDC = 2,6-naphthalic acid, H2BPnDC = 4,4′-carbonyldibenzoic acid, H2OBA = 4,4′-oxidibenzoic acid, and H4ODAC = 3,3′,4,4′-oxidibenzene tetracarboxylic acid).The complexes were characterized by single crystal and powder X-ray diffractions, IR, elemental and thermogravimetric analysis. All of them possess different three-dimensional (3D) frameworks based on MĲII)–L two-dimensional layers, which are further connected by auxiliary dicarboxylates with distinct bridging-angles and coordination numbers to obtain the final frameworks. Complex 1 is a (3,4)-connected 3D framework with gwg topology, while 2 and 3 are isostructures with a (4,4)-connected 2-fold interpenetrating 3D net. In the case of 4, it possesses a (4,4,4,4)-connected 3D architecture with a new topology.The desolvated samples 2′ and 3′ have adsorption capacities of H2O/MeOH/EtOH, while sample 4′ has remarkable selective adsorption for H2O/MeOH over EtOH.
