The title Schiff base compound, C(13)H(16)N(3)O(+)·PF(6) (-), was derived from the condensation of 2-hydroxy-benaldehyde with the ionic liquid 1-(2-amino-ethyl)-3-methyl-imidazolium hexa-fluoro-phosphate in an ethanol solution. The asymmetric unit comprises one cation and two PF(6) (-) anions. The dihedral angle between the aromatic and imidazole rings is 15.2 (2)°. An intra-molecular O-H⋯N hyd...

The asymmetric unit of the title organic salt, 2C(3)H(5)N(2) (+)·C(10)H(6)O(6)S(2) (2-), consists of an imidazolium cation and half a naphthalene-1,5-disulfonate dianion, completed to the full dianion through an inversion center. N-H⋯S and N-H⋯O hydrogen bonds link cations and anions in the crystal, forming a chain propagating along [101].

Abstract. Proton exchange membrane (PEM) electrolysis is one of the waters splitting techniques available for producing green hydrogen. As such, improvement ion conductivity will result in hydrogen production. Ionic liquids have recently been reported to enhance ionic PEM. Herein, a screening method select suitable development efficient proton membrane. COnductor-like Screening MOdel Realistic ...

The reaction of methylcarbonate ionic liquids with H2S or H2Se offers a highly selective synthesis of analytically pure, well-defined and soluble hydrosulphide and hydroselenide organic salts of general interest. Among them, imidazolium hydrochalcogenides show an astonishingly high volatility for cation-aprotic ILs, which allows their quantitative sublimation below 100 °C/10(-2) mbar and actual...

In the cation of the title compound, C(21)H(16)N(3)O(2) (+)·NO(3) (-), the N atom in the 3-position of the imidazole ring is protonated. The three pendant aromatic rings are twisted from the plane of the imidazolium ring by dihedral angles of 22.75 (1), 79.63 (1) and 29.65 (1)°. In the crystal structure, N-H⋯O hydrogen bonds link the mol-ecules, forming an infinite one-dimensional chain paralle...

This work describes the experimental and theoretical investigation of nonlinear optical properties imidazolium cation based ionic liquids corresponding thermo-optical parameters.

Theoretical simulations linear performed density functional theory (DFT) discussed in terms ...

The effects of interionic hydrogen bonding and π-π stacking interactions on the physical properties of a new series of picrate anion based ionic liquids (ILs) have been investigated experimentally and theoretically. The existence of aromatic (C2-HO) and aliphatic (C7-HO-N22 and C6-HO-N20) hydrogen bonding and π-π stacking interactions in these ILs has been observed using various spectroscopic t...

A thorough characterization of the structural properties of alkylimidazolium halide ionic liquids (ILs), namely 1-alkyl-3-methylimidazolium bromide ([Cnmim]Br with n = 5, 6, 8, 10) and iodide ([C6mim]I), has been carried out by combining molecular dynamics simulations and EXAFS spectroscopy. The existence of a local order in [Cnmim]Br ILs has been evidenced, with anions and imidazolium head gro...

The asymmetric unit of the title compound, (C(13)H(15)N(2)S(2))[RuCl(3)(C(10)H(14))], contains a 1,3-(2-thienylmeth-yl)-4,5-dihydro-imidazolium cation and a trichlorido(η(6)-p-cymene)ruthenate(II) anion. The thio-phene rings of the cation are disordered by an 180° rotation about the thio-phene-CH(2) bonds with occupancies of 0.847 (5)/0.153 (5) and 0.700 (5)/0.300 (5), respectively. The Ru atom...
