The crystal structure of (4E)-2-amino-3-cyanobenzo[b]oxocin-6-one, denoted as 4(E)-ACBO, was analyzed using X-ray diffraction technique. The dielectric and AC electrical conductivity measurements of the bulk 4(E)-ACBO in the form of pellet were studied in the range of frequency 42 Hz to 5 MHz and the temperature range of 303 K to 373 K. The temperature and frequency dependence of dielectric constant (ε₁), dielectric loss (ε₂) and AC electrical conductivity (δ ε_AC) were investigated. The relaxation time (τ) for electrons to hop over a barrier of height W_H was calculated at different temperatures. The AC activation energy was determined from the temperature dependence of δ _AC at different frequencies.
