✦ Synopsis
The title compound, C~16~H~36~N^+^·C~8~H~5~N~2~O~2~S^−^, crystallizes with two formula units in the asymmetric unit. In both anions, the oxadiazole ring is almost coplanar with the 2-hydroxyphenyl ring. The anion structure is influenced by intramolecular O—H...N hydrogen bonding. The crystal packing is stabilized by intermolecular C—H...S, C—H...O, C—H...N and C—H...π interactions. One butyl group is disordered over two positions, with site-occupancy factors of ca 0.6 and 0.4.
