Reactivity of Sulphuryl Chloride in Acetonitrile with the Elements
Woolf, Alfred A.
, p. 3325 - 3330 (1991)
Sulphuryl chloride in MeCN reacts with all but the most refractory elements to give mainly solvated chlorides at or below 300 K in contrast with SO2Cl2 alone which requires at least twice this temperature.There is evidence for an ionic mechanism based on analogy, thermochemistry, transport measurements and additive effects.The instability of these solutions leading to polymerization, together with its inhibition, is described.Sulphur dioxide formed in reactions seldom plays a reductive role apart from influencing formation of the mixed-valence Tl4Cl6.Semiquantitative kinetic measurements in different solvents emphasize the uniqueness of MeCN.For most elements attack is diffusion controlled across surface films giving a parabolic dependence on time which can be linearized if film growth is prevented by changing the solvent mix.The varied nature of these surface films vitiates any simple relation between rate and periodicity.Some applications are indicated.

Dithionitronium hexachloroantimonate(V), (S2N)(SbCl6), has been prepared by the reactions of S7NH, S7NBCl2, and 1,4-S6N2H2 with SbCl5 in liquid SO2. The structure of the compound has been determined by single-crystal X-ray diffraction. The orthorhombic crystal, space group I222, has cell dimensions a = 9.299 (3) ?, b = 7.976 (3) ?, and c = 7.070 (2) ? and has two formula units in the unit cell. Intensities were measured using Mo Ka radiation and a Syntex P21 diffractometer. The crystal structure was determined by standard methods and refined to R1 - 0.0377, R2 = 0.0375. The crystal is composed of linear S2N+ cations (N-S = 1.464 (3) ?) and approximately octahedral SbCl6- anions (Sb-Cl = 2.351 (3), 2.363 (2) ?). Infrared and Raman spectra of the solid compound are reported.

The reaction of S8O and SbCl5 in CS2 gave S8O*SbCl5 (71percent yield) which was shown by X-ray crystallography to contain S8O in an isomeric conformation compared with pure S8O which can be recovered from the adduct in its usual conformation by recrystall

A series of Ca2Sb2O7:xBi3+ (x = 0, 0.5, 1, 1.5, 2, 4 and 8 mol%) blue phosphors were synthesized using a chemical co-precipitation technique with further calcination. The X-ray diffraction (XRD) and scanning electron microscope (SEM) results revealed that the obtained Ca2Sb2O7:xBi samples are orthorhombic weberite structure with particle size ranging from 20 nm to 40 nm. X-ray photoelectron spectroscopy (XPS) confirmed that the introduction of bismuth into the Ca2Sb2O7 crystal was in the form of Bi3+ and no other chemical states were found. The Bi-doped Ca2Sb2O7 powders exhibit a broad emission band centered at 438 nm upon UV-irradiation and it is characterized by double-luminescence centers. The dependence of the luminescent intensity on the Bi-doping concentration in Ca2Sb2O7 was studied in detail. As a result, the optimized concentration of Bi3+ is 1.5 mol% for the highest emission intensity peaking at 438 nm, and the concentration quenching occurs when the concentration of Bi3+ exceeds 1.5 mol%. The luminescence mechanism of Bi3+ in Ca2Sb2O7 was also discussed. The favorable luminescent properties of Ca2Sb2O7:Bi3+ make it promising for lighting and display applications.

, p. 579 - 582 (1993)
C60 was doped with SbCl5 by the direct reaction with liquid SbCl5 or with SbCl5 dissolved in CCl4. Mass spectrometer analysis showed that the compound consisted of Cl2, SbCl3 and C60. The SbCl5 was removed by sublimation leaving Cl2 in C60. The doped compound was electrically conducting at room temperature. The resistivity increased with decreasing temperature corresponding to a semiconducting energy gap of 1.1 eV.

Hybrid organic-inorganic perovskite materials have demonstrated great potential in the field of photovoltaics and photoelectronics. On the basis of the high degree of structural flexibility and compatibility, diverse molecular functional materials have been assembled by modifying the length of the organic components and/or dimensionality of the inorganic frameworks. In this paper, we present a chiral lead-free organic-inorganic hybrid, (piperidinium)2SbCl5 (1), which follows the one-dimensional inorganic frameworks of the corner-sharing SbCl6 octahedra. Strikingly, 1 displays a dielectric phase transition at Tc = 338 K, changing from the chiral space group of P212121 to polar Pna21 upon heating. Crystal structure analyses reveal that an unusual thermally activated conformation change of the piperidinium cations affords the driving force to the phase transition of 1. That is, organic piperidinium moieties display a chairlike conformation below Tc, which transforms to a boatlike structure above Tc. Such an unprecedented change is strongly coupled to the dielectric transition along with notable steplike anomalies, which suggest that 1 could be used as a potential switchable dielectric material. Besides, the temperature-dependent conductivity and theoretical analysis of its electronic structure disclose the semiconducting behavior of 1. This study paves the pathway to the design of new lead-free semiconducting perovskites with targeted properties for optoelectronic application.

A pure inorganic uranyl phosphate-polyoxometalate of Na17{Na@[(SbW9O33)2(UO2)6(PO3OH)6]}·xH2O (abbreviated as Na@U6P6, with x ≈ 46) featuring a sandwich-type structure was prepared using Keggin-type trilacunary [α-B-SbW9O33]9- units as building blocks, which were formed in situ by SbCl3 and Na2WO4·2H2O. Crystal structural analysis showed that six UO22+ cations and six PO3OH2- anions generated a wheel-like cluster unit with a Na+ center ([Na@(UO2)6(PO3OH)6]+) that is stabilized by two [α-B-SbW9O33]9- units. Na@U6P6 displayed a solid-state photoluminescence quantum yield of 33% at 300 K. The temperature-dependent fluorescence emission spectra showed that Na@U6P6 has temperature-sensitive fluorescence in which its emission intensity decreased by 77% as the temperature increased from 200 to 300 K. These results suggest that such uranyl phosphate-polyoxometalate clusters could serve as potential temperature-sensitive molecular materials.
