In this article, the authors carry out a pioneering study of monocrystalline TlInS2 < 5% C > at higher than room-temperatures using impedance spectroscopy. It is shown that in TlInS2 < 5% C > crystals at temperatures higher than 400 K, the nature of conductivity is predominantly ionic. Moreover, characteristics of impedance spectra behavior of TlInS2 < 5% C > monocrystal samples were studied using the measurement frequency range of 25-10(6) Hz. For the measured frequency range, it is shown that curves of active and reactive impedance components undergo a dispersion characterized by decreasing values of Z ' and Z ' ', as the frequency of the electric field and radiation dose increases.
