Abstract: Molecular complexes of the charge-transfer (CT) type 5- or 6-aminoindazole Schiff bases with chloroanilic acid, dichlorodicyano-p-benzoquinone, and chloranil have been prepared and investigated by IR and electronic spectra. The type of bonding between the donors and acceptors depends on the nature of both components. The change of electrical conductance with temperature for some CT complexes was also studied aiming to clarify their semiconductor behaviour. The current— electric potential dependence was also studied and indicated an ohmic character.
