Abstract

The title compound is an azo-Cr complex (S-34Na) used as a charge-control agent in electrophotography. A high thermal stability of S-34Na has been investigated from the standpoint of the crystal structure. X-ray analysis revealed that S-34Na is a dinuclear complex of octahedral CrIII and NaI units and forms a one-dimensional polymer running along the c axis, contributing to a significant thermal stability of S-34Na. On the other hand, the electrical conductivity of S-34Na at about 100 °C is found to be higher than that of room temperature by three orders of magnitude. This supports our charge-control mechanism that assumes an appreciable temperature increase at the “toner/carrier” interface due to tribo-electrification.
