Bis(2-bromoethyl)ammonium bromide
The title salt, C(4)H(10)Br(2)N(+)·Br(-), crystallizes with four cations and four anions in the asymmetric unit. In the crystal, the bis-(2-bromo-eth-yl)ammonium cations and bromide anions are linked into chains by N-H⋯Br hydrogen bonds describing a binary C(2) (1)(4) motif along [010]. Each of these chains is formed by a unique cation and anion pair. The ammonium cations occur in the less pref...

Phase equilibrium studies of the Lewis acid-base systems AlCl,/PyH Br and AlBr,/PyHI indicate the existence of congruently melting compounds of the molar ratios 1:1 and 2:3 . These results are quite different from those of our studies of the A lCl3/PyHCl and the AlBrVPyHBr system s, in which four compounds in the molar ratios 1:1, 1:2, 1:3, and 2:3 could be detected. The melting point of pyridi...

In the title mol-ecular salt, C(15)H(17)N(2)O(+)·Br(-), the benzene and pyridinium rings form a dihedral angle of 83.0 (1)°. In the crystal, N-H⋯Br and N-H⋯O hydrogen bonds link the components into chains along [010]. These chains are linked by weak C-H⋯O and C-H⋯Br hydrogen bonds, forming a three-dimensional network.
متن کاملCrystal structure of 3-amino-1-propylpyridinium bromide
The title mol-ecular salt, C8H13N2 (+)·Br(-), crystallizes with two independent 3-amino-pyridinium cations and two bromide anions in the asymmetric unit (Z' = 2). In the pyridine ring, the N atom is alkyl-ated by a propyl group. The dihedral angle between the mean planes of the pyridinium ring and the propyl group is 84.84 (2)° in cation A, whereas the corresponding angle is 89.23 (2)° in catio...
متن کاملDual responsive supramolecular amphiphiles: guest molecules dictate the architecture of pyridinium-tailored anthracene assemblies.
By introducing an electron-deficient guest molecule and a counter anion, the assembly morphology of 1-[11-(2-anthracenylmethoxy)-11-oxoundecyl]pyridinium bromide (2-AP) was transformed to microsheets and nanofibers from microtubes, respectively.
