N-Methyl- and N-Ethylbenzhydrylamine Hydrochloride

The title compounds, MBH (C₁₄H₁₆N⁺.Cl⁻) and EBH (C₁₅H₁₈N⁺.Cl⁻), respectively, act as inhibitors of smooth-muscle spasms. Both compounds crystallize in enantiomorphous space groups but EBH presents two crystallographically inequivalent enantiomers. In both cases, the molecular conformation can be classified as deformed helical C_s. Both compounds form infinite chains along b through two types of N—H...Cl bond.
