The aymmetric unit of the title compound, C(8)H(18)N(+)·Cl(-), consists of one crystallographically independent 1-methyl-1-propyl-pyrrolidinium cation and one chloride anion, both of which lie in general positions. Minor hydrogen-bonded C-H⋯Cl inter-actions occur. However, no classical hydrogen bonding is observed.

The recent remarkable achievements in terms of efficiency performance and stability hybrid organic–inorganic perovskite solar cells (PSCs) are notably obtained by optimizing the A-site cation composition formamidinium-based 3D perovskites. As methylammonium chloride is ubiquitously employed precursor solution for very high PSC, purpose present paper to unveil exact role (MA+), chloride, solvent...

An N-H⋯Cl hydrogen bond connects the ions in the title salt, C(18)H(16)NO(+)·Cl(-). The quinolin-1-ium residue is almost planar (r.m.s. deviation = 0.020 Å) but both the acetyl group [O-C-C-C torsion angle = 62.73 (17)°] and adjacent benzene ring [C-C-C-C torsion angle = -104.06 (14)°] are twisted out of this plane; the acetyl and benzene substituents are non-parallel [dihedral angle = 66.16 (7...

more detailed explanation of the basis for MCIA's position. Woodruff et al. (1) incorrectly suggest that industrial air emissions of methyl chloride present a significant health risk. On the basis of 1990 data for the Toxics Release Inventory (TRI) and the Cumulative Exposure Project (CEP), Woofruff et al. purport to identify listed hazardous air pollutants (HAPs) that are present in the enviro...

In this protocol, 3-(2-carboxybenzoyl)-1-methyl-1H-imidazol-3-ium chloride [Cbmim]Cl and sulfonic acid functionalized pyridinium chloride [pyridine-SO3H]Cl as a new, reusable, and green Brønsted acidic ionic liquid (BAIL) catalyst were synthesized and successfully used for the one-pot ring opening of epoxide with sodium azide (NaN3) in water at room temperature. Epoxides under ring-opening easi...

background: the purpose of this work was to investigate the use of polyvinyl chloride (pvc) dyed with methyl red as a high dose radiation dosimetry. materials and methods: commercial pvc films from sabic made from resins pvc57s with thickness of 60 µm and methyl red with a molecular weight of 269.31 were used. irradiation was carried out using a 60co γ-ray generator with sources arranged in rec...

Airborne measurements of the halogenated trace gases methyl chloride, methyl bromide and chloroform were conducted over the Atlantic Ocean and 1000 km of pristine tropical rainforest in Suriname and French Guyana (3–6 • N, 51–59 • W) in October 2005. In the boundary layer (0–1.4 km), maritime air masses initially low in forest hy-5 drocarbons, advected over the forest by southeasterly trade win...
