2,6-Diisopropyl-anilinium chloride.

The title compound, C(12)H(20)N(+)·Cl(-), crystallizes with the chloride anions situated on twofold axes, while the cation is on a general position. All conventional hydrogen-bond donors and acceptors are utilized, forming a hydrogen-bonded ladder motif along the c axis. Investigation of the torsion angles between aromatic systems and isopropyl groups reveals unusual geometrical features. One isopropyl groups exhibits an expected eclipsed conformation with respect to the aromatic ring. The other isopropyl group shows a slight twist with respect to the aromatic ring. The short Cl⋯HC(methine) contact (2.88†à ) observed in the asymmetric unit is the probable reason for the twist feature around the isopropyl area.
