1-Bromomethyl-4-aza-1-azoniabicyclo[2.2.2]octane bromide
The title compound, C(7)H(14)BrN(2) (+)·Br(-), was prepared by nucleophilic substitution of DABCO (systematic name: 1,4-diaza-bicyclo-[2.2.2]octa-ne) with dibromo-methane in acetone. The structure features Br⋯H close contacts (2.79 and 2.90 Å) as well as a weak bromine-bromide inter-action [3.6625 (6) Å].

In the crystal structure of the title compound, C(8)H(14)N(3) (+)·Br(-)·2H(2)O, inter-molecular O-H⋯O and O-H⋯Br hydrogen bonding occurs. The water mol-ecules are connected into chains extending in the a-axis direction. The bromide anions are connected to the water mol-ecules, forming 10-membered rings. The cations are connected to the anions via weak C-H⋯Br inter-actions. Two carbon atoms of t...

In the crystal of the title mol-ecular salt, C(7)H(7)N(2) (+)·Br(-), the cations form inversion dimers via weak pairwise C-H⋯N hydrogen bonds; their mean planes are separated by 0.292 (6) Å. Weak C-H⋯Br inter-actions involving all of the remaining H atoms tie the cations and anions together into sets of inter-penetrating sheets. The title compound is isostructural with its iodide analogue.

In the title compound, C(14)H(13)N(2) (+)·Br(-), the 1-(4-cyano-benz-yl)-4-methyl-pyridinium cation has a Λ-shaped conformation, and the dihedral angle between the benzene and pyridinium rings is 75.8 (2)°. In the crystal, two cations form a dimer through π-π inter-actions between pyridine rings [the centroid-centroid distance is 3.685 (1) Å].
متن کامل1-{2-[4-(4-Nitrophenyl)piperazin-1-yl]ethyl}-4-aza-1-azoniabicyclo[2.2.2]octane iodide
The title compound, C(18)H(28)N(5)O(2) (+)·I(-), was observed as a main product in an intended 1:1 reaction between 4-iodo-nitro-benzene and 1,4-diaza-bicyclo-[2.2.2]octane (DABCO). In the reaction, DABCO undergoes a ring opening to yield a quaternary salt of DABCO and 1-ethyl-4-(4-nitro-phen-yl)piperazine with an iodide anion. The crystal structure determination was carried out as no crystal s...
