Structure and Molecular Motions in Rubidium Tetraphenylborate
By X-ray diffraction it was found that at 293 K the crystals of rubidium tetraphenylborate are tetragonal, space group I4̄2m, a = b = 11.212(2) Å, c = 8.098(2) Å, with 2 molecules of Rb[C24H20B] # in the unit cell. The molecular reorientations as functions of temperature were studied by H NMR. Two types of motions were detected: an anisotropic reorientation of the tetraphenylborate anions about ...
متن کاملCrystal structure control of aluminized clay minerals on the mobility of caesium in contaminated soil environments
Radioactive caesium pollution resulting from Fukushima Dai-ichi and Chernobyl nuclear plant accidents involves strong interactions between Cs+ and clays, especially vermiculite-type minerals. In acidic soil environments, such as in Fukushima area, vermiculite is subjected to weathering processes, resulting in aluminization. The crystal structure of aluminized clays and its implications for Cs+ ...
متن کاملCrystal structure of caesium dihydrogen citrate from laboratory X-ray powder diffraction data and DFT comparison
The crystal structure of caesium di-hydrogen citrate, Cs+·H2C6H5O7-, has been solved and refined using laboratory X-ray powder diffraction data, and optimized using density functional techniques. The coordination polyhedra of the nine-coordinate Cs+ cations share edges to form chains along the a-axis. These chains are linked by corners along the c-axis. The un-ionized carb-oxy-lic acid groups f...
متن کاملN-(Diphenylselenio)diphenylsulfimidium tetraphenylborate.
The title compound, C24H20NSSe+.C24H20B-, exhibits disorder (S/Se scrambling) of the chalcogen sites within the S-N-Se triad. Similar disorder was observed in the bromide salt [Aucott, Bailey, Elsegood, Gilby, Holmes, Kelly, Papageorgiou & Pedron-Haba (2004). New J. Chem. pp. 959-966]. The S-N and Se-N bond lengths are 1.6735 (15) and 1.8045 (14) A, respectively. Whereas the chalcogens in the b...
متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
