The electronic structure of 2:3 neutral/radical mixed TCNQ complexes was studied by mean of the optical measurements performed on the crystals at various temperatures and pressures. The crystals of the complexes were also grown under the influence of high magnetic field, and the effects of magnetic field applied during the crystal growth were also studied similarly. The complexes have electronic structure of organic semiconductor where the disorders in the molecular columns consist of neutral/radical TCNQ molecules plays important role in determining the structure.
