In the crystal structure of the title molecular salt, C(6)H(14)N(+)·Br(-), N-H⋯Br hydrogen bonds link the cations and anions to form a one-dimensional network.

The asymmetric unit of the title salt, C(7)H(10)N(+)·Br(-), comprises two 2,6-dimethyl-pyridinium cations and two bromide anions. One cation and one anion are situated in general positions, while the other cation and the other anion lie on a crystallographic mirror plane parallel to (010). Each pair of ions inter-act via N-H⋯Br and C-H⋯Br hydrogen bonding, generating motifs depending on the cat...

In the title compound, C(6)H(5)N(2) (+)·Br(-), the pyridine N atom is protonated and involved in an inter-molecular N-H⋯Br hydrogen bond which, together with weak C-H⋯N hydrogen bonds, results in the formation of a chain along the c axis. Weak inter-molecular C-H⋯Br inter-actions between pyridine H atoms and Br(-) anions connect these chains into a network parallel to the bc plane.

In the title compound, C(9)H(14)N(+)·Br(-), an intra-molecular N-H⋯Br inter-action links the anion to the cation. In the crystal structure, inter-molecular N-H⋯Br inter-actions link the mol-ecules into a three-dimensional network.

Methyl bromide is a highly toxic gas with poor olfactory warning properties. It is widely used as insecticidal fumigant for dry foodstuffs and can be toxic to central and peripheral nervous systems. Most neurological manifestations of methyl bromide intoxication occur from inhalation. Acute toxicity characterized by headache, dizziness, abdominal pain, nausea, vomiting and visual disturbances. ...

Bromides were formerly used for their sedative and anti-convulsant properties. The neuropsychiatric features of bromide intoxication have been recognized for many years (Barbour, Pilkington and Sargent, 1936). Carney (1971) described 5 cases of bromism and advocated stricter control on bromide preparations. Part III of the Medicine Act (1978) made potassium bromide available only by prescriptio...

X-ray absorption spectroscopy (XAS) has been used to unveil the bromide ion local coordination structure in 1-alkyl-3-methylimidazolium bromide [C(n)mim]Br ionic liquids (ILs) with different alkyl chains. The XAS spectrum of 1-ethyl-3-methylimidazolium bromide has been found to be different from those of the other members of the series, from the butyl to the decyl derivatives, that have all ide...

Circular dichroism in the 300-360 nm region and fluorescence induced by intercaltating binding of ethidum bromide to both DNA and RNA components were studied in isolated HeLa nucleoli. Both DNA and RNA compoents contribute to the induced dichroic elliticity. Digestion of nucleoli by RNase or DNase shows that most of the induced ellipticity comes from the DNA component. In nucleoli with an RNA/D...

Information regarding solute and water transport as affected by soil properties, topography, and climatic conditions is required to improve and validate transport models. This study evaluated the dissipation of bromide applied to the soil surface in the fall and spring to undisturbed (eroded) and rehabilitated landforms, in which topsoil was moved from depositional areas to the eroded upper slo...

The propellant-free Combivent Respimat Soft Mist Inhaler (CVT-R) was developed to replace the chlorofluorocarbon-propelled Combivent metered-dose inhaler (CVT-MDI). This steady-state pharmacokinetic (PK) substudy evaluated drug lung-delivery efficiency, using data from two phase III safety and efficacy trials. PK parameters were obtained from well-controlled population PK analyses. Area under t...
