Metal-organic frameworks (MOFs), infinite systems built up of metal ions and organic ligands have been extensively studied in materials and supramolecular chemistry due their structural diversity and application as porous materials, in catalysis, ion exchange, gas storage and purification. [1] A novel, 2-fold interpenetrated, pillared, cadmium metal-organic framework was synthesized using trimesic acid and 1,2-bis(4-pyridyl)ethane.[2] Single crystal X-ray analysis revealed a 2-fold interpenetrated, 3-dimensional framework which exhibits a 3,5-connected network with the Schläfli symbol of [(6^3)(6^9.8)] and hms topology. This compound exhibits a temperature-induced single-to-crystal-single-crystal (SC–SC) transformation upon the release of N,N'-dimethylformamide (stable up to 3000C). SC–SC transformation was also observed when the desolvated form absorbed selected polar and non-polar organic solvents. In addition, gas (N_2, CO_2 and N_2O) sorption experiments were performed showing 2.5% N_2, 4.5% CO_2 and 3.4% N_2O absorption by mass at room temperature and moderate gas pressures (~10 bar). A similar MOF was produced when 1,3,5-benzenetricarboxylic acid was replaced with 5-nitro-1,3-benzenedicarboxylic acid. This MOF displays 4-fold interpenetration and also maintains the host framework structure upon heating.

<div> <p>Post-synthetic modification (PSM) of metal–organic frameworks (MOFs) is an important strategy for accessing MOF analogues that cannot be easily synthesized <i>de novo</i>. In this work, the rare-earth (RE) cluster-based MOF, Y-CU-10, with <b>shp</b> topology was modified through transmetallation using a series of RE ions, including: La(III), Nd(III), Eu(III), Tb(III), Er(III), Tm(III), and Yb(III). In all cases, metal-exchange higher than 70 % was observed, with reproducible results. All transmetallated materials were fully characterized and compared to the parent MOF, Y-CU-10, in regards to crystallinity, surface area, and morphology. Additionally, single-crystal X-ray diffraction (SCXRD) measurements were performed to provide further evidence of transmetallation occurring in the nonanuclear cluster nodes of the MOF. </p> </div>
