Al-Fumaric Acid MOF, nke a na-akpọkarị Al-FUM, bụ Metal Organic Framework (MOF) ji usoro kemịkal ya bụ Al (OH) (fum) .xH.2O, ebe x dị ihe dịka 3.5 na FUM na-anọchite anya ion fumarate. Al-FUM na-ekerịta usoro isoreticular na MIL-53 (Al) -BDC a ma ama, yana BDC guzo maka 1,4-benzenedicarboxylate. A na-ewu MOF a site na agbụ nke nkuku octahedra nke na-ekerịta nkuku nke jikọtara fumarate ligands, na-emepụta pores nke nwere ụdị lozenge nke nwere akụkụ efu nke ihe dịka 5.7 × 6.0 Å.2.
