Methyl bromide is a highly volatile liquid which disperses rapidly and readily. As a fumigant it ranks amongst the most efficient because of its extremely effective penetrating power and absence of fire or explosion hazard. It is, unfortunately, highly toxic and poisoning occurs readily in circumstances of careless or inadvertent exposure. Before 1940, only 42 cases of methyl bromide poisoning ...

IN THE TITLE COMPOUND [SYSTEMATIC NAME: (4R,4aS,7aR,12bS)-3-cyclo-propyl-meth-yl-4a,9-hy-droxy-7-oxo-2,3,4,4a,5,6,7,7a-octa-hydro-1H-4,12-methano-benzofuro[3,2-e]isoquinolin-3-ium bromide methanol monosolvate], C(21)H(26)NO(4) (+)·Br(-)·CH(3)OH, two of the three six-membered rings adopt chair conformations while the third, which contains a C=C double bond, adopts an approximate half-boat confor...

In the crystal of the title salt, C8H10NO2 (+)·Br(-), the bromide anions and the phenylglycinium cations are -linked through N-H⋯Br, O-H⋯Br and C-H⋯O hydrogen bonds, generating sheets lying parallel to (001).

In the cation of the title compound, C(7)H(7)N(2) (+)·Br(-), the nitrile group and the benzene ring are almost coplanar (r.m.s. deviation = 0.0043 Å). In the crystal, the cations and anions are connected by inter-molecular N-H⋯Br hydrogen bonds, forming a two-dimensional network parallel to (010).

In the title compound, C(6)H(7)ClN(+)·Br(-), the amino N atom is protonated. All non-H atoms of the cation are essentially coplanar [r.m.s. deviation = 0.004 (3) Å]. In the crystal, N-H⋯Br hydrogen bonds connect the ions, forming a ribbon-like structure propagating along [010].

In the cation of the title compound, C(7)H(7)N(2) (+)·Br(-), all non-H atoms are essentially coplanar [r.m.s. deviation = 0.010 (5) Å]. The compound is isomorphous with the chloride analogue. In the crystal, the cations and anions are connected by N-H⋯Br hydrogen bonds.
