Add-Ons
MIL-88A(Fe) (Fe3O(X)(H}2O)2(fumarate)3, where X = OH- or Cl-; fumarate = trans-butenedicarboxylate) is a flexible, iron-based metal-organic framework with an acs topology. Constructed from inorganic u3-oxo-centered iron trimers (Fe3O) cross-linked by short, linear fumaric acid linkers, it forms 1D hexagonal and bipyramidal diamond channels known for reversible "breathing" transitions under guest inclusion.
For Gas Absorption & Separation, the key structural features of the MIL-88A(Fe) are: (1) Extreme Framework Flexibility ("Breathing Effect"): MIL-88A exhibits dynamic lattice expansion without bond breaking: Dried / Closed Form (Contracted): Unit cell volume contracts upon desolvation, with narrow pore channels (< 3 Å) that can appear virtually non-porous to 77 K N2. Solvated / Open Form (Expanded): Guest interaction with the polar iron trimer triggers an expansion of the unit cell volume by up to ~ 85–100%, opening the hexagonal channels up to ~ 6.0–8.0 Å. (2) Lewis Acidic / Redox-Active Fe^{3+}/Fe^{2+} Sites: Coordination-unsaturated iron sites on the Fe3O trimers provide strong electrostatic interaction and π-backbonding capabilities for polar and unsaturated gases. (3) Green & Biocompatible Composition: Built entirely from non-toxic iron and fumaric acid (an endogenous metabolic intermediate), MIL-88A provides high biocompatibility for medical gas storage/delivery (NO, CO) and green industrial scrubbing.
