Abstract: In the title salt, C18H24NO+·C6H7O7-, the dihedral angle between the benzene rings in the cation is 74.2 (5)°. In the crystal, anion-anion O-HO hydrogen bonds and weak O-HO interactions form infinite chains along . Between these chains, cation-anion N-H-O hydrogen bonds are observed, forming an alternate pattern of cation and anion layers and leading to a two-dimensional network parallel to (100).
