“…MIL-53-In was synthesized according to the literature method. 32 In(NO 3 ) 3 xH 2 O (0.194 g, 0.50 mmol) and DHBDC (0.148 g, 0.75 mmol) were ultrasonically separated into a Teflon kettle containing DMF (4.00 mL), H 2 O (1.00 mL), HF (40%, 0.03 mL) and HClO 4 (70%, 0.22 mL). Then the solution was heated at 80 °C for 16 hours (yield: 43%, based on In).…”

“…Knowing the magnitude of electronegativity and the size of the M ions makes it possible to search for new compounds with a specific composition and structure or to explain the unreality of their preparation, including the conversion of MIL-53(M 3+ ) into another type of MOF or the production of non-single-phase samples subject to the synthesis conditions (Table 1). Thus, phases with M 3+ = V (r V VI = 0.64Å, χ V = 1.53) [13], Sc (r Sc VI = 0.745Å, χ Sc = 1.19) [14], and In (r In VI = 0.8Å, χ In = 1.66) [15], and are obtained by the hydrothermal method under different conditions (temperature, duration of the process) and synthesis than those presented in Table 1 which crystallize in other types of structures.…”

This article presents a crystal chemical analysis, generalization, and systematization of structural characteristics of metal-organic polymers MIL-53(M3+) with M = Al, Cr, Ga, and Fe. The division of the MIL-53(M3+) structures into a morphotropic series was performed, which made it possible to predict the formation of new compounds or solid solutions with the corresponding composition and structure. The change in the symmetry of MIL-53(M3+) and the causes of polymorphs formation are explained on the basis of crystal chemical rules. The efficiency of the revealed regularities in the structural characteristics of the MIL-53(M3+) phases were experimentally confirmed for MIL-53(Fe) and composite MIL-53(Fe)/GO (GO-graphene oxide) by several methods (powder X-ray, X-ray absorption, and photoelectron spectroscopy). For the first time, different coordination numbers (CN) (CNFe = 4.9 for MIL-53(Fe)—two types of coordination polyhedra with CNFe = 6 and CNFe = 4; CNFe = 4 for MIL-53 (Fe3+)/GO) and the formal charges (FC) of iron ions (variable FC of Fe (2+δ)+ in MIL-53(Fe3+) and Fe2+ in MIL-53(Fe3+)/GO) were found. These experimental data explain the higher photocatalytic activity of MIL-53(Fe3+)/GO in photo-Fenton reactions—RR195 decomposition.

Isoreticular Chemistry of Group 13 Metal–Organic Framework Compounds Based on V-Shaped Linker Molecules: Exceptions to the Rule?

Following the concept of isoreticular chemistry, we carried out a systematic study on Ga-containing metal−organic frameworks (MOFs) using six V-shaped linker molecules of differing sizes, geometries, and additional functional groups. The linkers included three isophthalic acid derivatives (m-H 2 BDC-R, R = CH 3 , OCH 3 , NHCOCH 3 ), thiophene-2,5-dicarboxylic acid (H 2 TDC), and two 4,4′-sulfonyldibenzoic acid derivatives (H 2 SDBA, DPSTA). The crystal structures of seven compounds were elucidated by a combination of model building, single-crystal X-ray diffraction (SCXRD), three-dimensional electron diffraction (3D ED), and Rietveld refinements against powder X-ray diffraction (PXRD) data. Four new Ga-MOFs that are isoreticular with their aluminum counterparts, i.e. Ga-CAU-10-R (Ga(OH)(m-BDC-R); R = OCH 3 , NHCOCH 3 ), Ga-CAU-11 (Ga(OH)(SDBA)), and Ga-CAU-11-COOH (Ga(OH)(H 2 DPSTC)), were obtained. For the first time large single crystals of a MOF crystallizing in the CAU-10 structure type could be isolated, i.e. Ga-CAU-10-OCH 3 , which permitted a detailed structural characterization. In addition, the use of 5-methylisophthalic acid and thiophene-2,5-dicarboxylic acid resulted in two new Ga-MOFs denoted Ga-CAU-49 and Ga-CAU-51, respectively, which are not isostructural with any known Al-MOF. The crystal structure of Ga-CAU-49 ([Ga 4 (m-HBDC-CH 3 ) 2 (m-BDC-CH 3 ) 3 (OH) 4 (H 2 O)]) contains an unprecedented rod-shaped inorganic building unit (IBU) of the formula ∞ 1 {Ga 16 (OH) 18 O 60 }, composed of corner-sharing GaO 5 and GaO 6 polyhedra. In Ga-CAU-51 ([Ga(OH)(C 5 H 2 O 2 S)]) chains of alternating cis and trans corner-sharing GaO 6 polyhedra form the IBU. A detailed characterization of the title compounds was carried out, including nitrogen gas and water vapor sorption measurements. Ga-CAU-11 was the only compound exhibiting porosity toward nitrogen with a type I isotherm, a specific surface area of a S,BET = 210 m 2 /g, and a micropore volume of V mic = 0.09 cm 3 /g. The new MOF Ga-CAU-51 exhibits exceptional water sorption properties with a reversible S-shaped isotherm and a high uptake around p/p 0 = 0.38 of m ads = 370 mg/g.
