“…The lack of evidence of hydrogen bonding with the terminal nitrido ligand of the anion implies that it has low nucleophilicity. This correlates with the short Mn≡N bond length [1.536(2) Å], which is comparable to those found in related complexes and coordination frameworks 22–25…”

“…The calculated heats of adsorption show essentially identical results for both MOFs (Figure b), with the values remaining near constant about 15 kJ/mol up to a loading of 1 mmol/g. These values for the heats of adsorption are low compared to values for other polar groups in the literature , and are more consistent with the sorption of CO 2 onto itself . This might indicate that the CO 2 molecules are unable to interact with high energy sites in the framework, such as the sulfur or oxygen atoms.…”

In the dipolar form, the atoms of the dimethylthiocarbamate groups are coplanar and the adjacent methyl group might have a shielding steric influence on the sulfur or oxygen atoms ability to interact with CO 2 .…”

. (2016). High temperature postsynthetic rearrangement of dimethylthiocarbamate-functionalized metal-organic frameworks. Crystal Growth and Design, 16 (12),[7067][7068][7069][7070][7071][7072][7073] High temperature postsynthetic rearrangement of dimethylthiocarbamatefunctionalized metal-organic frameworks AbstractA thermally promoted postsynthetic rearrangement has been performed on a zinc IRMOF-9-type framework bearing dimethylthiocarbamate tag groups. The rearrangement was accomplished via conventional heating at 285 °C. Crucially, despite the high temperature, the MOF maintains its high accessible surface area and pore space following thermal treatment. The structures and physical properties of the frameworks were characterized by a combination of single-crystal X-ray diffraction, powder X-ray diffraction, differential thermal-thermogravimetric analysis, and gas sorption analysis. The rearrangement results in a slightly higher level of CO 2 adsorption for the modified MOF but with equivalent heat of adsorption. This work offers new perspectives on postsynthetic rearrangements in MOFs and demonstrates that rearrangements that occur at relatively high temperatures are still compatible with the need to retain the structural integrity and porosity of the framework.

“…As a result, this framework has a solvent accessible volume of 73% and a BET surface area of 1020 m 2 g À1 upon freeze-drying activation. Networks with pts-topology were also observed for metallo linkers with tetrahedral geometry 104,105 and tetratopic linkers with twisted tetrahedral conformations. 106,107…”

Tuning the structure and function of metal–organic frameworks via linker design

et al. 2014

Metal-organic frameworks (MOFs) are constructed from metal ions/clusters coordinated by organic linkers (or bridging-ligands). The hallmark of MOFs is their permanent porosity, which is frequently found in MOFs constructed from metal-clusters. These clusters are often formed in situ, whereas the linkers are generally pre-formed. The geometry and connectivity of a linker dictate the structure of the resulting MOF. Adjustments of linker geometry, length, ratio, and functional-group can tune the size, shape, and internal surface property of a MOF for a targeted application. In this critical review, we highlight advances in MOF synthesis focusing on linker design. Examples of building MOFs to reach unique properties, such as unprecedented surface area, pore aperture, molecular recognition, stability, and catalysis, through linker design are described. Further search for application-oriented MOFs through judicious selection of metal clusters and organic linkers is desirable. In this review, linkers are categorized as ditopic (Section 1), tritopic (Section 2), tetratopic (Section 3), hexatopic (Section 4), octatopic (Section 5), mixed (Section 6), desymmetrized (Section 7), metallo (Section 8), and N-heterocyclic linkers (Section 9).

A porous Mn(v) coordination framework with PtS topology: assessment of the influence of a terminal nitride on CO2 sorption

Abstract: A new coordination framework material, [Zn{MnN(CN)4(H2O)}]·2H2O·MeOH, has been characterised crystallographically and the effect of a terminal nitride on the N2, H2 and CO2 sorption capacities of the material assessed through porosimetery measurements and DRIFTS.
