Tetra­butyl­ammonium 2,6-di­hydroxy­benzoate 2,6-di­hydroxy­benzoic acid solvate

The title compound, C16H36N+·C7H5O4−·C7H6O4 or (nBu4N)+·(2,6-dhb)−·(2,6–Hdhb) [where (nBu4N) is tetra­butyl­ammonium, (2,6-dhb)− is 2,6-di­hydroxy­benzoate and (2,6-Hdhb) is 2,6-di­hydroxy­benzoic acid], crystallizes in the space group P1. The crystal structure involves alternate layers, in the c direction, of cationic [nBu4N]nn+ and anionic [(2,6-dhb)(2,6-Hdhb)]nn−. Hydro­gen bonds within the anionic layers form bridges between 2,6-Hdhb and 2,6-dhb− residues.
