摘要

Three new metal organic frameworks (MOFs) based on hetero-O, N donor ligands, (Cu4I4) [Cu-2(PDC)(2)-DMF2](2)center dot 2DMF center dot H2O (JLU-Liu15), (Cu4I4)[Cu-3(CPNA)(3)(Dabco)(0.5)DMF3]center dot 4DMF center dot 4H(2)O (JLU-Liu16), and (Cu4I4)-[Cu-3(CPNA)(3)(H2O)(0.5)DMF3]center dot 4DMF.4H(2)O (JLU-Liu17), (H2PDC = pyridine-3,5-dicarboxylic acid, H(2)CPNA = (5-(4'-carboxylphenyl) nicotinic acid, Dabco = 1,4-diazabicyclo[2.2.2]octane), have been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction analyses. JLU-Liu15 features a (3,4,4)-c sqc5588 net, whereas JLU-Liu16 and JLU-Liu17 are isostructural and possess a new (3,4,4)-c topology. All of these compounds are composed of the binodal inorganic Cu-2(CO2)(4) paddlewheel and Cu4I4 cluster secondary building units (SBUs). It is worthy to note that the linkage between two nearby Cu4I4 clusters in JLU-Liu16 is mu(2)-Dabco, which changed to a mu(2)-water molecule in JLU-Liu17. Furthermore, JLU-Liu15 exhibits high CO2 adsorption behaviors as well as I-2 uptake and release features.
