N-[2-(4-Bromo­benzo­yl)eth­yl]isopropyl­aminium chloride

The crystal structure of the title compound, C₁₂H₁₇BrNO⁺·Cl⁻, is stabilized by N—H...Cl and C—H...O hydrogen bonds, forming a three-dimensional network. The inter­actions framework is completed by C—H...π contacts between a methyl­ene group and the benzene ring of a symmetry-related mol­ecule.

N-(2-Benzoyl­eth­yl)propan-2-aminium chloride

In the title salt, C₁₂H₁₈NO⁺·Cl⁻, N—H...Cl inter­actions between the free chloride anions and the organic cations connect the mol­ecules into hydrogen-bond dimers, forming a R₂²(8) motif. The dimers are linked by C—H...O hydrogen bonds into chains extending along [301]. The carbonyl group is co-planar with the phenyl ring [C—C—C=O torsion angle = −3.3 (7)°]. The side chain has an E conformation.

N-[2-(4-Methyl­benzo­yl)eth­yl]propan-2-aminium chloride

In the title compound, C₁₃H₂₀NO⁺·Cl⁻, the protonated amino N atom is hydrogen bonded to the chloride anion. N—H...Cl hydrogen bonds link the anions and cations into dimers, which are connected by C—H...O hydrogen bonds, forming supra­molecular chains extending along [100].
