The title compound, (C10H21N3)[CuCl4], is composed of one 1-[2-(di-ethyl-aza-nium-yl)eth-yl]-3-methyl-imidazolium dication and a tetra-chlorido-cuprate(II) dianion. The anion adopts a distorted tetra-hedral geometry. Bifurcated interionic N-H⋯Cl hydrogen bonds and several C-H⋯Cl contacts are observed, leading to a layer-like arrangement of the components parallel to (100).

Mixtures containing ammonia-borane and sec-butylamine-borane remain liquid throughout the hydrogen release process that affords tri(N-sec-butyl)borazine and polyborazylene. Concentrated solutions with metal catalysts afford >5 wt% H(2) in 1 h at 80 °C and addition of (EMIM)EtSO(4) ionic liquid co-solvent eliminates competing formation of insoluble linear poly(aminoborane) (EMIM = 1-ethyl-3-meth...

The liquid-liquid equilibrium for the ternary system formed by n-octane and aromatic (alkylbenzenes) and heteroaromatic compounds (nitrogen and sulfur containing heterocyles) and 1-alkyl-3-methylimidazolium ionic liquids (ILs) associated with various anions has been investigated. The selectivity on the extraction of a specific aromatic compound is influenced by anion volume, hydrogen bond stren...

In the cation of the title salt, C(6)H(8)N(4) (2+)·C(8)H(2)Br(3)NO(4) (2-), the dihedral angle between the two five-membered rings is 2.1 (3)°. In the anion, the mean planes of the carboxyl units are twisted from the benzene ring by 84.3 (4) and 86.2 (3)°. In the crystal, the components are linked by imidazolium-carboxyl-ate N-H⋯O hydrogen bonds, generating a chain running along [10].

A marked inhibition of the incorporation of S(35)-sulfate by normal calf costal cartilage was produced by potassium ascorbate in the presence of catalytic amounts of cupric ions. The effect of the various components of the ascorbic acid oxidizing system (potassium ascorbate, cupric ions, cuprous ions, hydrogen peroxide, dehydroascorbic acid) was investigated. The results of experiments in which...

High-pressure infrared measurements were carried out to observe the microscopic structures of two imidazolium-based ionic liquids, i.e., 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide [EMI(+)(CF(3)SO(2))(2)N(-), EMI(+)TFSA(-)] and 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)amide [EMI(+)(FSO(2))(2)N(-), EMI(+)FSA(-)]. The results obtained at ambient pressure indicate that the ...

Dynamic tribochemical processes for dicationic ionic liquid containing a germinal 14 imidazolium cation head groups bridged by a poly(ethylene glycol) and 15 bis(trifluoromethylsulfonyl)imide anion were studied using time-resolved Mechanically 16 Stimulated Gas Emission Mass-Spectrometry (MSGE-MS). In comparison with similar 17 monocationic imidazolium ionic liquids with short alkylic or long p...

In the title compound, C(19)H(19)N(4)O(2) (+)·Cl(-)·C(2)H(3)N, the dihedral angle between the two phenyl rings is 69.57 (8)° while the dihedral angles between the imidazole ring and the phenyl rings are 70.61 (7) and 82.11 (7)°. In the crystal, N-H⋯Cl, C-H⋯O, C-H⋯Cl and C-H⋯N hydrogen bonds link the imidazolium cations, chloride anions and acetonitrile solvent mol-ecules into a two-dimensional ...
