X-ray diffraction pattern of 4-aminoantipyrine was studied and it is a single phase with a polycrystalline structure. 4-aminoantipyrine has hexagonal structure with space group P6/mcc. The electrical properties of 4-aminoantipyrine were studied in the temperature range (303-373 K) below the melting point of the studied compound and in the frequency range (100 Hz-100 kHz). The obtained results of dc conductivity showed a positive temperature coefficient at the lower temperatures and a negative temperature coefficient at the higher temperatures. The ac conductivity obeys the power law. Ac conductivity can be reasonably interpreted in terms of overlapping-large polaron tunneling model and the correlated barrier hopping model. 4-aminoantipyrine is a good candidate for electronic device due to its electrical conductivity and capacitance.
