The infrared absorption spectra of the InxTl1-xJ -system layered crystals are studied. The essential changes in their structure are observed, depending on the content of thallium component. These changes are related to isostructural phase transition. A role of free charges in the structural transformations is discussed.

Keywords: layered crystals, infrared spectroscopy, transmittance spectra, isostructural phase transition.
