Abstract

The title compound, C16H26NO2+center dot-C7H5O2-, is a benzoate salt of the painkiller Tramadol. The six-membered cyclohexane ring of the cation adopts a slightly distorted chair conformation and carries OH and 3-methoxyphenyl substituents at the 2-position and a protonated methylazaniumylmethyl group at the 3-position. In addition, a weak intramolecular C-H center dot center dot center dot O hydrogen bond is observed in the cation. In the crystal, weak O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the components into chains along 010]. A C-H center dot center dot center dot pi contact is also observed.
