Cyclobenzaprinium chloride

Abstract

In the title molecular salt [systematic name: 3-(5H-dibenzo[a,d]cyclohepten-5-ylidene)-N,N-dimethylpropanaminium chloride], C20H22N+·Cl−, two cation–anion pairs make up the asymmetric unit. The dihedral angles between the mean planes of the two fused benzene rings of the cation are 49.5 (1) and 50.9 (1)°. The cystal packing is stabilized by N—H...Cl hydrogen bonds and weak C—H...Cl interactions.
