The title compound (P-51) is a well-known charge-control agent (CCA) used widely in electrophotography. Structure analysis as well as electrical measurements has been carried out in the present study in order to support our charge-control mechanism that assumes an appreciable temperature increase at the "toner/carrier" interface. P-51 is found to crystallize in space group of P2_I/n. There are chains of OH ‥O intermolecular hydrogen bonds between the OH group of one anion and the O atom of the other, leading to a polymer-like stabilization of the anion. The electrical conductivity increases exponentially with temperature by two-three orders of magnitude in the temperature range between room temperature and 100 °C. The present temperature dependence is closely correlated with the molecular arrangement as well as charging characteristics of the toner which includes P-51.
