The temperature dependence of the electric conductivity, the magnetic sus-ceptibility and the ESR spectra of the crystals of an organic ion-radical salt,1,1'-diethyl-2,2'-cyanine-[7,7',8,8'-tetracyanoquinodimethanel., were measured.The electric conductivity, o, is fairly large at room temperature (a.j=3.50 'cm ') and shows a semiconductive temperature dependence, of whichactivation energy decreases with decreasing temperature. The susceptibilityobeys Curie-Weiss' law above 60 K and shows a maximum near 40 K. Below 15 Kthe susceptibility increases again with decreasing temperature. However, similarlyat high temperatures even at 4.2 K there are two intense ESR absorptions ofwhich interval depends on the orientation of the crystal in the applied magneticfield.
