A Zr(IV)-based metal-organic framework (MOF), termed reo-MOF-1 [ZrO(HO)(SNDC)], composed of 4-sulfonaphthalene-2,6-dicarboxylate (HSNDC) linkers and ZrO(HO)(CO) clusters was synthesized by solvothermal synthesis. Structural analysis revealed that reo-MOF-1 adopts the reo topology highlighted with large cuboctahedral cages (23 Å). This structure is similar to that found in DUT-52 (fcu topology), however, reo-MOF-1 lacks the body-centered packing of the 12-connected ZrO(OH)(CO) clusters, which is attributed to the subtle, but crucial influence in the bulkiness of functional groups on the linkers.
