Antimony is one of the key fission products in the reprocessing of spent nuclear fuel by the fluoride volatility method because of the high volatility of antimony fluorides. Since the fluorination reaction of antimony compounds is not well understood, the reaction behavior of antimony compounds with F2 was investigated by thermogravimetric and differential thermal analyses and X-ray diffraction analysis in this study. The target antimony compounds were antimony metal, SbF3, Sb2O3, Sb2O4, and Sb2O5. The fluorination reaction of antimony metal started at 150 °C, and the fluorination product was SbF3. SbF3 volatilized completely by the reaction with F2 above 190 °C; it was considered that volatile SbF5 was formed by the reaction with F2. In the series of fluorination of the antimony oxides, Sb2O3, Sb2O4, and Sb2O5, they started to react with F2 and volatilize at 330 °C as SbF5. During the fluorination of Sb2O3, Sb2O4 was formed temporarily in the course of the reaction. Oxygen released from the fluorination reaction of a part of Sb2O3 would oxidize remained Sb2O3 to Sb2O4. The reaction mechanism for the fluorination of antimony compounds obtained in this study is applicable to evaluate the transfer of antimony in the reprocessing process of the fluoride volatility method.

Four antimony fluoride sulfates named A2SO4·SbF3 (A = Na+, NH4+, K+, Rb+) have been successfully synthesized using a hydrothermal method by introducing Sb3+ cations with a stereochemically active lone pair in sulfates and subsequently tuning the structure through the second monovalent cations. All of the title compounds are stoichiometrically equivalent materials which share a common structural motif composed of a distorted SO4 tetrahedron and an asymmetric SbF3 polyhedron. However, the macroscopic centricities of these four compounds are significantly influenced by the size and coordination environment of cations; Na2SO4·SbF3 crystallizes in centrosymmetric space groups Cmca and (NH4)2SO4·SbF3 in Pbca, while K2SO4·SbF3 and Rb2SO4·SbF3 crystallizes in noncentrosymmetric space group P212121. Complete characterization including thermal analyses, infrared and UV-vis spectroscopy, and theoretical calculations is also reported. Powder second harmonic generation measurement for noncentrosymmetric K2SO4·SbF3 and Rb2SO4·SbF3 indicated that both of them are type I phase-matchable.

Complexes of the formula MSb2BrF4O (M = K, Rb, and NH4) were obtained from aqueous solutions of SbF3 and MBr and examined by chemical analysis, X-ray diffraction, thermal analysis, and IR, Raman, and 19F NMR spectroscopy. It was found that the red reflectance is 74-97% and the UV reflectance is 7-15%. The highest averaged reflectance (93%) was observed for KSb2BrF4O. The decomposition temperatures of MSb2BrF4O (M = K, Rb, and NH4) are 230, 197, and 223°C, respectively. Pleiades Publishing, Ltd., 2012.

Reactions between Se/Te mixtures and AsF5 or SbF5 and between Se4(AsF6)2 and Te4(AsF6)2 have been investigated with the aim of preparing new mixed Se/Te cations. Among the crystalline products isolated and characterized by X-ray crystallography were (Te2Se4)(Sb3F14)(SbF6) (1), (Te2.7Se3.3)(SbF6)2 (2), (Te3.4Se2.4)(SbF6)2 (3), and new crystal forms of (Te2Se4)(MF6)2 [M = As (4), Sb (5)]. Similar reactions of Te/S mixtures gave the compound (Te2.1S3.9)(SbF6)2 (6), which is isomorphous with 5 and contains the cation Te2S42+. Compounds 2 and 3 are isomorphous with the previously reported form of (Te2Se4)(SbF6)2. In all six compounds the cations are six-membered rings in the boat conformation with two tellurium atoms forming a cross-ring bond, that is, a bicyclo[3.1.0]hexane type arrangement. Occupational disorder in compounds 2 and 3 and anion-cation interactions are discussed. Crystal data are as follows: 1, orthorhombic, space group Pbca, a = 15.288 (5) ?, 6 = 17.189 (5) ?, c = 17.300 (5) ?, V = 4546 ?3; 2, orthorhombic, P212121, a = 12.192 (2) ?, b = 8.770 (2) ?, c = 15.817 (2) ?, V = 1697 ?3; 3, orthorhombic, P212121, a = 12.266 (3) ?, b = 8.828 (3) ?, c = 15.884 (4) ?, V = 1720 ?3; 4, orthorhombic, Pna21, a = 23.775 (6) ?, b = 8.663 (3) ?, c = 15.168 (4) ?, V = 3124 ?3; 5, orthorhombic, Pbcn, a = 12.124 (4) ?, b = 18.493 (6) ?, c = 29.503 (7) ?, V = 6614 ?3; 6, orthorhombic, Pbcn, a = 11.988 (3) ?, b = 18.220 (6) ?, c = 29.096 (8) ?, V = 6355 ?3.
Attempted Synthesis of Osmium(VI) and Iridium(VI) Thiofluorides; the Preparation of OsF5.SF4 and IrF5.SF4

The interaction of OsF4 or IrF4 with ZnS or B2S3 at elevated temperature yields the adducts OsF5.SF4 and IrF5.SF4 rather than the trasition-metal thiofluorides.Infrared and X-ray powder diffraction studies indicate that the adducts have contributions to the bonding from the ionic formulations +- and +- and there is also (19)F n.m.r. evidence for the latter in solution in anhydrous HF.

The X-ray crystal structures of [IBr2][Sb2F11] and [IBr0.75Cl1.25][SbCl6] have been determined from diffractometer data by the heavy-atom method. Crystals of [IBr2][Sb2F11] are orthorhombic, space group Pbca, with a = 14.445 (7) ?, b = 14.034 (5) ?, c = 12.725 (3) ?, V = 2580 (1) ?3, and dcalcd = 3.81 g cm-3 for Z = 8. Crystals of [IBr0.75Cl1.25][SbCl6] are triclinic, space group P1, with a = 7.084 (1) ?, b = 6.299 (1) ?, c = 13.511 (3) ?, α = 94.50 (2)°, β = 100.32 (2)°, γ = 92.56 (2)°, V = 590.3 (2) ?3, and dcalcd = 3.18 g cm-3 for Z = 2. The structures were solved by Patterson and Fourier methods and refined by full-matrix least squares to R1 = 0.065 and R2 = 0.064 for 1390 observed (I > 2σ(I)) reflections for [IBr2][Sb2F11] and R1 = 0.061 and R2 = 0.075 for 2360 observed (I > 2σ(I)) reflections for [IBr0.75Cl1.25][SbCl6]. Both structures consist of infinite chains of cations and anions such that the iodine in each cation achieves a trapezoidal four-coordination via cis bridges to the anions. In [IBr2][Sb2F11] the I-Br distances average 2.423 (3) ? and the bridging I-F distances are 2.845 (12) and 2.782 (12) ?. The disordered cation [IBr0.75Cl1.25]+ has one terminal interaction at 2.427 (2) ?, very close to the I-Br distance in [IBr2]+, while the other terminal distance is 2.373 (3) ?, much longer than the I-Cl distance (2.268 (2) ?) in the [ICl2]+ cation. The bridging I-Cl distances in the disordered cation average 2.952 (2) A. The Raman data are interpreted in terms of these structures and are compared to related literature data.
