Triethylammonium 3,4-dihydroxybenzoate

Abstract

In the title compound, C6H16N+·C7H5O4−, the hydroxy groups of the 3,4-dihydroxybenzoate anion form O—H...O hydrogen bonds to the carboxylate groups of two adjacent anions, generating layers propagating in the ac plane. The triethylammonium cations lie between these layers, forming N—H...O hydrogen bonds to the carboxylate groups of the anions. The structure is consolidated by weak intermolecular C—H...O interactions.
