“…The crystal components form a three-dimensional supra­molecular network via N—H⋯O, C—H⋯O and C—H⋯π inter­actions. A comparison of the conformations of the levomepromazine cations with those of the neutral mol­ecule and similar protonated mol­ecules reveals significant conformational flexibility of the pheno­thia­zine ring system and the substituent at the pheno­thia­zine N atom.…”

“…The ester moiety has an extended conformation and is almost in the same plane with respect to the isoxazole ring, as indicated by the O—C—C—N torsion angle of −172.86 (18)°. In the crystal, mol­ecules are linked via pairs of C—H⋯O hydrogen bonds with the same acceptor atom, forming inversion dimers with two R (2) (1)(7) ring motifs. …”
