N-(2,6-Diisopropyl­phen­yl)formamide toluene 0.33-solvate

The crystal packing of the title compound, C₁₃H₁₉NO·0.33C₇H₈, shows a channel at [001], which contains grossly disordered toluene solvent mol­ecules. The angle between the benzene ring and the mean plane of the formamide group is 71.1 (1)°. The amide groups of neighbouring mol­ecules are connected by N—H...O hydrogen bonds, forming 2₁ helical chains propagating along [001]. Mol­ecules are also connected by weak inter­molecular C—H...O hydrogen bonds, forming 6₁ helices.

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

In the title compound, C₂₇H₃₇N₂⁺·Cl⁻·2CH₂Cl₂, the cation and the anion are each located on a crystallographic mirror plane. Both of the dichloro­methane solvent mol­ecules show a disorder across a mirror plane over two equally occupied positions. Additionally, one isopropyl group is also disordered. In the crystal, the cations are connected to the chloride ions via C—H...Cl hydrogen bonds.

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.
