2-Methyl-5,6-dinitrobenzimidazolium chloride
In the title compound, C(8)H(7)N(4)O(4) (+)·Cl(-), the cation possesses twofold symmetry, with the twofold axis bis-ecting the 2-methyl-5,6-dinitro-benzimidazolium cation. The methyl H atoms are disordered about this twofold axis and were assigned equal half-occupancies. The chloride anion also lies on a twofold axis. In the crystal, N-H⋯Cl and C-H⋯O hydrogen bonds link the ions to form a three...
متن کاملN-Methyl-4-nitroanilinium chloride
The asymmetric unit of the title salt, C(7)H(9)N(2)O(2) (+)·Cl(-), contains two independent cations and anions. In the crystal, each N-methyl-4-nitro-anilinium cation is linked to two Cl(-) anions via N-H⋯Cl hydrogen bonds. π-π stacking is observed between the benzene rings of adjacent cations [centroid-to-centroid distances = 3.7684 (14) and 3.7917 (7) Å].
متن کامل1-Methyl-1-propylpyrrolidinium chloride
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.

background: traditional cigarette advertising has existed in the us for over 200 years. studies suggest that advertising has an impact on the initiation and maintenance of smoking behaviors. in recent years, electronic cigarettes (e-cigarettes) emerged on the market as an alternative to the traditional tobacco cigarette. the purpose of this study was to describe advertisements in popular us mag...
متن کاملSolvent effects on the intramolecular conversion of trimethylsulfonium chloride to dimethyl sulfide and methyl chloride.
The formation of CH3Cl from (CH3)3SCl in various solvents has been studied based on M05/6-311+G(2d,p) DFT calculations to quantify the influence of the solvent on the stability of sulfonium cations. Four different pathways (one SN1, one backside and two frontside attacks for SN2) as well as the formation of different ion pairs (tripod, seesaw, and linear) are discussed to investigate the origin...
