7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthren-1-yl)methanaminium 4-toluenesulfonate

In the title compound, C20H32N+ center dot C7H7O3S-, the configurations of the two chiral centers observed in the protonated cation are consistent with previous reports. In the crystal structure, weak intermolecular N-H center dot center dot center dot O hydrogen bonds link ions into chains which develop along the a axis. The isopropyl group and four CH groups of the attached benzene ring are disordered approximately equally over two positions.
