title: Benzyl-tributyl-ammonium 7-hydroxy-naphthalene-1-sulfonate.
abstract: The title compound, C(19)H(34)N(+)·C(10)H(7)O(4)S(-), is a charge-control agent used for toners in electrophotography. The anions form one-dimensional chains by O-H⋯O hydrogen bonds in a zigzag fashion along the c axis between the OH group of one anion and the sulfonate O atom of a neighboring anion. One of the n-butyl chains of the cation is disordered over two sites in a 0.77:0.23 ratio.
