title: Benzyl-tributyl-ammonium 4,6-dihydroxy-naphthalene-2-sulfonate.
abstract: The title mol-ecular salt, C(19)H(34)N(+)·C(10)H(7)O(5)S(-), 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.
