Hydrogen bonding in ionic liquids based on the 1-(2'-hydroxylethyl)-3-methylimidazolium cation (C(2)OHmim) and various anions (A) of differing H-bond acceptor strength, viz. hexafluorophosphate PF6, tetrafluoroborate BF4, bis-(trifluoro ...
Two new isostructural layered oxohalides FeTe3O7X (X = Cl, Br) were synthesized by chemical vapor transport reactions, and their crystal structures and magnetic properties were characterized by single-crystal X-ray diffraction, Raman spectroscopy, magnetic ...
A series of fluorescent imidazolium-based salts contg. the cation [AnCH2MeIm]+ (in which An=anthracene and Im=the imidazolium cation) with Cl-, BF4-, PF6-, SO3CF3-, [N(CN)2]-, [N(SO2CF3)2]-, or PhBF3- anions have been prepd. and characterized. X-ray diffra ...
The title compound, C10H18, a decalin stereoisomer, crystallizes with Z' = 0.5 in the space group P21/n. The trans-decalin molecule is located on an inversion centre with both rings in a chair conformation, making for a quasi-flat overall shape. Despite th ...
The title compound, C5H10N2S5, was unintentionally obtained as the product of an attempted synthesis of a methyl-carbamodithioic acid using methylamine and carbon disulfide. In the molecule, two dithiocarbamate groups are bridged by a -CH2S- unit. The C-S- ...
A large series of ionic liqs. (ILs) based on the weakly coordinating alkoxyaluminate [Al(hfip)4]- (hfip: hexafluoroisopropoxy) with classical as well as functionalized cations were prepd., and their principal phys. properties detd. M.ps. are between 0 ([C4 ...
We present here the structure of Yer0l0c protein of unknown function, solved by Multiple Anomalous Diffraction and revealing a common fold and oligomerization state with proteins of the regulator of ribonuclease activity A (RraA) family. In Escherichia col ...
A surfactant-free synthesis of mesoporous and hollow silica nanoparticles is reported in which boron acts as the templating agent. Using such a simple and mild procedure as a treatment with water, the boron-rich phase is selectively removed, affording meso ...
Pizgrischite, (Cu,Fe)Cu14PbBi17S35, is a new mineral species named after the type locality, Piz Grisch Mountain, Val Ferrera, Graubunden, Switzerland. This sulfosalt occurs as thin, striated, metallic lead-grey blades measuring up to I cm in length, embedd ...
The thermally induced hysteretic spin transition (ST) that occurs in the polymeric chain compound Fe(NH(2)trz)(3)(2) (1) above room temperature (T-c(sic) = 347 K, T-c(sic) = 314 K) has been tracked by Fe-57 Mossbauer spectroscopy, SQUID magnetometry ...
