(4-Chlorophenyl)methanaminium chloride hemihydrate

Abstract

In the title hydrated salt, C7H9ClN+·Cl−·0.5H2O, the water O atom lies on a crystallographic twofold axis. In the crystal, the monoprotonated 4-chloro­benzyl­ammonium cation forms N—H⋯Cl and N—H⋯O hydrogen bonds and the water mol­ecule forms O—H⋯Cl hydrogen bonds, generating layers lying parallel to the bc plane.

“…Furthermore, the crystal structure is stabilized by C1-H1BÁ Á Á iii and C8-H8AÁ Á Á i weak interactions involving the C2-C7 benzene ring, to form a threedimensional network (see Table 1). Souissi et al (2010) have reported the crystal structure of (4-chlorophenyl)-methanaminium chloride hemihydrate, in which the water O atom lies on a crystallographic twofold axis.…”
