Benzyltributylammonium 4,6-dihydroxynaphthalene-2-sulfonate

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—H...O hydrogen bonds. Further O—H...O 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.
