The local electronic state of Te in the helical chains of CuXY_{2(1-x)}Te_{2x} (X = Cl, Br; Y = Se, S) were studied using the Mössbauer spectroscopy of ^{125}Te at 10 K and 70 K. The isolated chains of Te in these compounds are less rigid than those in elemental Te. The determined data of quadrupole splittingΔ and Debye temperatureΘ_D are indicative of strong local ordering of Te in one of the two non-equivalent crystallographic positions. It was not possible to resolve crystallographic positions by the Mössbauer spectroscopy.
