4-(o-Tolyl)piperazin-1-ium chloride

Abstract

In the title mol-ecular salt, C<inf>11</inf>H<inf>17</inf>N<inf>2</inf> +·Cl-, the piperazin-1-ium ring adopts a chair conformation with the aromatic ring in a pseudo-equatorial orientation. The dihedral angle between the benzene ring and the mean plane of the piperazin-1-ium ring is 51.22 (6)°. In the crystal, N - H?Cl hydrogen bonds link the molecules into chains propagating in [100]. Weak C - H?? interactions also ocur. © Fun et al. 2011.
