Popis: An expanded pyridyl-decorated MOF-505 analogue[Cu2(L)(H2O)2]·G(x) (H4L = 5,5'-(pyridine-2,5-diyl)diisophthalic acid, G = solvent molecule) has been solvothermally synthesized and reported. It exhibited rare hierarchical meso- and microporosity. With exposed unsaturated Cu(II) sites and Lewis basic pyridyl sites, the material shows both large CO2-uptake capacity (123.4 cm(3) g(-1) at 273 K, 1 bar) and high selectivity for CO2 over N2 (55.7) at 273 K. Furthermore, for the first time the compound has been exploited for its heterogeneous catalytic performance toward the cyanosilylation reaction under solvent-free conditions. The compound can be recycled up to five times with only a minor loss of activity.
