2-[(Prop-2-yn-1-yl)amino]anilinium chloride

Abstract

The title compound, C9H11N2+·Cl−, is an anilinium chloride salt, in which the Car—N—C—C (ar = aromatic) torsion angle is −84.95 (18)°. In the crystal, a bilayer of cation–anion sheets runs parallel to (100), primarily through an extensive range of N—H...Cl hydrogen bonds. Weak offset π-stacking interactions between the benzene rings stack molecules along c.
