TL;DR: A new efficient synthetic method towards the elusive MIL-88B(Cr), yet reported only once without synthetic details, is proposed and has an interesting and potentially valuable property of retaining its high-volume form after thermal activation.
Abstract: The concentration of benzoic acid was found to exercise efficient control over the formation of either MIL-101(Cr) or MIL-88B(Cr) under otherwise similar hydrothermal synthetic conditions. Nanocrystals of MIL-101(Cr) with ∼100 nm average size and excellent SBET = 3467 m2 g−1 are obtained at lower concentrations of benzoic acid, while at higher concentrations the microparticulated MIL-88B(Cr) product is formed. Hereby a new efficient synthetic method towards the elusive MIL-88B(Cr), yet reported only once without synthetic details, is proposed. The obtained MIL-88B(Cr) has an interesting and potentially valuable property of retaining its high-volume form (Vcell ∼ 2000 A3) after thermal activation. The degassing of MIL-88B(Cr) in a vacuum at 250 °C yields a porous material with a SBET area of 1136 m2 g−1, which is around the theoretical maximum. The transition to the denser ‘closed’ form (Vcell ∼ 1500 A3) occurs only at 350 °C, when all of the benzoate/benzoic acid, hindering the process, is removed.

TL;DR: The synthesis and crystal structures of twelve new compounds containing the UO22+ cation, a bromo-substituted benzoic acid linker and a chelating N-donor were reported in this article.
Abstract: The syntheses and crystal structures of twelve new compounds containing the UO22+ cation, a bromo-substituted benzoic acid linker (m-bromo-, p-bromo, or 3,5-dibromobenzoic acid) and a chelating N-donor (1,10-phenanthroline, 2,2′:6′,2′′-terpyridine, or 4′-chloro-2,2′:6′,2′′-terpyridine) are reported Single crystal X-ray diffraction analyses of these materials allowed for the exploration of the structural relationship between the benzoic acids and the chelating N-donor, as well as the influence of pH on uranyl speciation At an unadjusted pH (∼3) a mix of uranyl monomers and dimers are observed whereas at higher pH (5–6) uranyl dimers are usually produced with monomers and tetramers also observed A systematic study of the supramolecular interactions present in these materials was executed by varying the bromine position on the benzoic acid groups along with substituents on the chelating N-donor Assembly via halogen and hydrogen bonding interactions as well as π–π interactions, including four instances of uranyl oxo-functionalization via halogen bonding, was observed depending on the experimental conditions utilized
