N,N-Di­methyl­dehydro­abietyl­ammonium chloride ethanol monosolvate

The title compound {systematic name: 1-[(1R,4aS,10aR)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octa­hydro­phenan­thren-1-yl]-N,N-di­methyl­methanaminium chloride ethanol monosolvate}, C(22)H(36)N(+)·Cl(−)·C(2)H(6)O, was synthesized from dehydroabietylamine by N-methyl­ation with formaldehyde/formic acid and transformation into the hydro­chloride. The de­hydro­abietyl moiety exhibits the usual conformation with the two cyclo­hexane rings in chair and half-chair conformations and a trans-ring junction. The crystal structure is built up from columns of the de­hydro­abietyl moieties stacked along the a axis. These columns are held together by the chloride ions via N—H⋯Cl and C—H⋯Cl inter­actions, which establish a two-dimensional network parallel to (010). The ethanol solvent mol­ecules are located between the columns and anchored via O—H⋯Cl hydrogen bonds.
