Crystal Structures of Bromobismuthate Complexes ((3-MePy)2C2)4[Bi2Br11][BiBr6] and (3-MePy)2C2[Bi2Br11](Br3)

Journal of Structural Chemistry, 2019
© 2019, Pleiades Publishing, Ltd. By the reaction of a [BiX6]3− solution in HBr with the bromide salt of bis-(3-methyl-1-pyridino)ethane ((3-MePy)2C2Br2) the bromobismuthate complex ((3-MePy)2C2)4[Bi2Br11][BiBr6] (1) is obtained, which, when kept in the Br2 solution in HBr, transforms into ((3-MePy)2C2)3 [Bi2Br11](Br3) (2).

Production and characterization of H3BO3–Li2CO3–K2CO3–MgO glass for dosimetry

Radiation Physics and Chemistry, 2015
Borate glasses are suitable for thermoluminescent dosimetry. In particular, borate glasses doped with different elements show good characteristics in terms of linearity, sensitivity and effective atomic number. However, these glasses are also hygroscopic, which can reduce their viability as dosimeters.

The crystal structures of Mg2Fe2C4O13, with tetrahedrally coordinated carbon, and Fe13O19, synthesized at deep mantle conditions

2015
We simulated the redox decomposition of magnesium-siderite at pressures and temperatures corresponding to the top of the Earth's D′′ layer (135 GPa and 2650 K). It transforms into new phases, with unexpected stoichiometry. We report their crystal structure, based on single-crystal synchrotron radiation diffraction on a multi-grain sample, using a ...

Synthesis and Luminescence of Sr1– x – yYbxEuyF2+ x + y Solid Solutions for Photonics

Inorganic Materials, 2019
© 2019, Pleiades Publishing, Ltd. Abstract—: Single-phase Sr1– x – yYbxEuyF2+ x + y solid solutions with an average particle size near 90 nm have been synthesized via co-precipitation from aqueous solutions, followed by high-temperature annealing. Efficient Yb3+ luminescence was observed upon excitation at a wavelength of 266 nm.

Labile η⁶-areneruthenium sulfide clusters. Crystal structure of [(C6H6)4Ru5S4](PF6)2 and [(C6H6)4Ru4S5](PF6)2

2018
© 2018 Elsevier B.V. A new labile areneruthenium sulfide complex, [(C6H6)3Ru3S2](PF6)2 (1), was prepared and characterized both in solid state and in solution. Light-driven de-coodination of the arene ligands has been demonstrated. Two new polynuclear areneruthenium complexes, [(C6H6)4Ru5S4](PF6)2·2CH3CN (2) and [(C6H6)4Ru4S5](PF6)2·1.25CH3CN·0.5H2O (3)
