Modulating the packing of [Cu24(isophthalate)24] cuboctahedra in a triazole-containing metal–organic polyhedral framework

Abstract

The highly porous (3,24)-connected framework NOTT-122 incorporates a C3-symmetric angularly connected isophthalate linker containing 1,2,3-triazole rings and shows body-centered tetragonal packing of [Cu24(isophthalate)24] cuboctahedra. This unique packing, coupled with the high density of free N-donor sites, is responsible for the simultaneous high H2, CH4 and CO2 adsorption capacities in desolvated NOTT-122a. © 2013 The Royal Society of Chemistry.
