Abstract: 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)]_n^n-. Hydrogen bonds within the anionic layers form bridges between 2,6-Hdhb and 2,6-dhb^- residues.
