TL;DR: A distinct step in the isotherm occurs during the adsorption of CO2 on MIL-53 at 304 K and it is suggested that a breathing behavior is induced in MIL- 53 during CO2 adsorptive activity.
Abstract: A distinct step in the isotherm occurs during the adsorption of CO2 on MIL-53 at 304 K. Such behavior is neither observed during the adsorption of CH4 on MIL-53 nor during the adsorption on the isostructural MIL-47. This phenomenon seems to be due to a different mechanism than that of previous adsorption steps on MOF samples. It is suggested that a breathing behavior is induced in MIL-53 during CO2 adsorption.

TL;DR: Loiseau et al. as discussed by the authors used 2,6-naphthalenedicarboxylic acid as a rigid ligand to synthesize a new three-dimensional aluminum-organic framework, MIL-69 or Al(OH)2 octahedra corner-linked through the μ2-hydroxyl groups.

TL;DR: A scandium terephthalate with isolated ScO6 octahedra and fully-linked carboxylate groups is prepared hydrothermally and possesses a novel hybrid framework structure with high thermal stability and a pore volume for N2 adsorption at 77 K.

TL;DR: In this article, a new zinc carboxylate Zn 3 (OH) 2 (bdc) 2 ·2DEF was synthesized under mild hydrothermal conditions (100°C, 40h) in the presence of 1,4-benzenedicarboxylic (BDc) acid, in N,N′ -diethylformamide (DEF) solvent.

TL;DR: In this paper, a gallium carboxylate Ga(OH)(btec)⋅0.5H2O was synthesized under mild hydrothermal conditions (200 °C, 24 hours) in the presence of 1,2,4,5-benzenetetracarboxylic acid and water.

TL;DR: A new aluminum fluoride, Al(2)F(8), was synthesized under mild hydrothermal conditions in the presence of 1,3,5-benzenetricarboxylic acid in pyridine/HF (pyr/HF) solvent and characterized with single-crystal XRD analysis and high-resolution solid-state NMR.
Abstract: A new aluminum fluoride, Al2F8·2NC5H6·C6H3(CO2H)3, was synthesized under mild hydrothermal conditions (200 °C, 3 days) in the presence of 1,3,5-benzenetricarboxylic acid (btc) in pyridine/HF (pyr/HF) solvent. Its structure is characterized with single-crystal XRD analysis and high-resolution solid-state NMR. The inorganic framework consists of the corner- and edge-shared connections of AlF6 octahedra. They are linked via a common edge and form a bioctahedral motif which is trans-connected through the corner-shared fluorine. It results in the formation of an original infinite double file of AlF6 octahedra running along the a axis. A high-power decoupled MAS 27Al{19F} Hahn echo NMR spectrum allowed us to distinguish the two crystallographic hexacoordinated Al sites. Four unresolved 19F NMR signals are observed in the MAS spectra to account for the eight crystallographic fluorine atoms. Half of the terminal fluorine sites interact via strong hydrogen bonds with the ammonium groups of the pyridine moieties. T...

TL;DR: A new layered gallium phosphate Ga10(PO4)2(HPO4)12(OH)5⋅2.5H2O was hydrothermally synthesized at 180°C for 3 days by using triethylenetetramine (teta) as structure-directing agent as discussed by the authors.

TL;DR: Crystals of the oxyfluorinated gallium phosphate MIL-12 (digallium phosphate pentafluoride propane-1,3-diaminium), (C3H12N2)[Ga2(PO4)F5], were synthesized hydrothermally at 453 K under autogenous pressure using propane’s role as the structure-directing agent.
Abstract: Crystals of the oxyfluorinated gallium phosphate MIL-12 (digallium phosphate pentafluoride propane-1,3-diaminium), (C 3 H 12 N 2 )[Ga 2 (PO 4 )F 5 ], were synthesized hydrothermally at 453 K under autogenous pressure using propane-1,3-diamine as the structure-directing agent. The title compound is isomorphous with the aluminium phosphate having the MIL-12 structural type. The structure is built up from a two-dimensional anionic network intercalated by the diamine species. The inorganic layer is composed of corner-linked GaO 2 F 4 octahedra and PO 4 tetrahedra. The diprotonated diamine group is located on a mirror plane, between the inorganic sheets, and interacts preferentially via hydrogen bonding through the ammonium groups and the terminal F and bridging O atoms of the inorganic layer. One of the Ga atoms lies on an inversion centre and the other lies on a mirror plane, as does the P atom, two of the phosphate 0 atoms and one of the F atoms.
