A three-dimensional (3-D) multi-functional mixed valence CuII/CuI-MOF, [Cu(CuI)2(2-pyzc)2H2O]2·H2O}n (Hpyzc = pyrazine-2-carboxylic acid), has been solvothermally synthesized and successfully characterized by FT-IR spectroscopy, elemental analysis, powder X-ray diffraction, thermal gravimetric analysis (TGA) and single-crystal X-ray diffraction. The structure posesses a 3-D open framework containing 1-D channels and shows a tcj topological network with the Schläfli symbol (43·612)(43)2. This MOF exhibits selective adsorption of CO2/H2 over CH4/N2 and excellent catalytic activity in the oxidation of benzylic compounds and three-component coupling reactions of aromatic alkynes, tosyl azide and diisopropylamine as a cooperative catalyst. The catalyst could be reused several times without significant degradation in catalytic activity.
