Benzyltributylammonium 4,6-dihydroxynaphthalene-2-sulfonate

K. Uta and J. Mizuguchi

Abstract: The title molecular salt, C₁₉H₃₄N⁺·C₁₀H₇O₅S^-, is a charge-control agent used for toners in electrophotography with a high melting point of 508 K. In the crystal structure, the anions form inversion dimers, linked by pairs of O-HO hydrogen bonds. Further O-HO links between dimers generate anionic sheets propagating in (010). One of the n-butyl chains of the cation is disordered over two sets of sites in a 0.53:0.47 ratio.
