The title compound (azo Fe-complex) is a well-known chargecontrol 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 is based upon local heating and charge transfer through conductive channels at the “toner/carrier” contact. Methanol or acetone-solvated single crystals were isolated from solution in methanol or acetone, respectively. The former is found to crystallize in space group of P-1 while P21/n in the latter crystal. The electrical conductivity of these crystals increases exponentially with temperature and the value around 100 °C is two-three orders of magnitude higher than that of room temperature.
