Abstract: Using ESR spectroscopy, it has been found that the additional paramagnetic centers appear in the (DOEO)$_4$[HgBr$_4$] $\cdot$ TCE crystals at temperatures of 5–70 K. The symmetry of their crystal field differs from that observed for charge carriers in a temperature range of 70–300 K. The comparison of the temperature dependences of resistivity with parameters of the ESR spectra makes it possible to assume that the carriers localize at two types of sites differing by the crystalline surrounding at 70 K.
