{"product_id":"cgasmof74mg","title":"MOF-74(Mg) Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOF74Mg","description":"\u003cp\u003eMOF-74(Mg) (also designated as Mg-MOF-74 or CPO-27-Mg, with chemical formula Mg2(DOBDC), where DOBDC = 2,5-dioxido-1,4-benzenedicarboxylate) is a honeycomb-topology metal-organic framework with an exceptionally high density of coordinatively unsaturated metal sites (open metal sites, OMS). Built from infinite helical chains of edge-sharing MgO6 octahedra cross-linked by 2,5-dihydroxyterephthalate linkers, it features 1D hexagonal channels with open Mg^{2+} cations that provide benchmark performance for low-pressure gas capture.\u003c\/p\u003e\n\u003cp\u003eThe critical structural and functional features of the MOF-74(Mg) are shown below: (1) \u003cstrong\u003e1D Hexagonal Honeycomb Channels\u003c\/strong\u003e: \u003cem\u003eChannel Diameter\u003c\/em\u003e: ~11.0–12.0 Å (accessible pore aperture ~ 10.5 Å. \u003cem\u003eOpen Metal Site Density\u003c\/em\u003e: Every Mg^{2+} ion in the coordination backbone points an open coordination site directly into the channel interior upon solvent removal, yielding a theoretical active site density of ~ 7.6 mmol\/g.
