Porous Lithium Imidazolate Frameworks Constructed with Charge‐Complementary Ligands

Biologically derived metal organic frameworks

“…[191] Recently, it has become of particular interest to create tetrahedral MOFs that would share structural topologies and coordination factors similar to zeolite chemistry. [194][195][196][197] Tetrahedral imidazolate frameworks (TIF) tetrahedrally coordinated with divalent cations (Zn II or Co II ) by the uni-negative (when an atom only accepts one electron) imidazolate ligands. [198][199][200][201][202] A new approach was taken by Zhang et al by adding an auxiliary uninegative ligand into a zinc-imidazolate tetrahedral assembly to generate tetrahedral frameworks with the formula Zn(Im)x(L2)2-x, where L2 is (Ade)(Int) in TIF-Al, (Im)3(Int) in TIF-A2 and (Im)(Int)2(OH) in TIF-A3.…”

A new metal–organic framework with potential for adsorptive separation of methane from carbon dioxide, acetylene, ethylene, and ethane established by simulated breakthrough experiments

“…[5][6][7][8][9][10][11][12][13][14][15] The rst examined MOF (ZIF-8) for C 2 s/C 1 separation by ExxonMobil exhibits quite a low separation capacity and selectivity. 28 We signicantly enhanced the separation capacity up to about 3.0 mol kg À1 and the selectivity up to 35 via tuning the pore and cavity sizes in the MOF UTSA-34 for C 2 s/C 1 separation.…”

Two 2D Metal‐Organic Networks based on s‐Block Metal Nodes (Li+ and Mg2+) and Rigid Imidazole/Carboxylate ­Functionalized Linkers

“…The bond angles around Li + ion range from 91.01 (19) + complexes containing coordinated imidazole or carboxylate groups. [21] The bond valance sum calculated for the lithium atom is 1.16 v.u., consistent with that of Li(I).…”
