1,3-Bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium bromide dichloromethane disolvate

In the title compound, C27H37N2 +·Br−·2CH2Cl2, both the cation and the anion are located on a crystallographic mirror plane. Both of the dichloromethane solvent molecules show a disorder across a mirror plane over two equally occupied positions. In the crystal, the cations are connnected to the bromide ions via C—H⋯Br hydrogen bonds.

The title compound crystallizes with discrete cations, anions and solvent dichloromethane molecules. Both cations and anions are located on a crystallographic mirror plane. Both dichloromethane molecules show a disorder across a mirror plane over two equally occupied positions. The Br anions are connnected to the cations via C-H···Br hydrogen bonds.
After two weeks at 253 K colorless needles of the title compound crystallized in the NMR-Tube.

Refinement
H atoms were refined using a riding model, with C-H ranging from 0.95 Å to 1.00 Å and with U iso (H) = 1.2U eq (C) or U iso (H) = 1.5U eq (C methyl ).  Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > σ(F 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
