organic compounds
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 Cs. Both compounds form infinite chains along b through two types of N—HCl bond.
