As a part of current systematic investigations of strontium tellurite, SrTeO3, with particular emphasis on crystal chemistry and phase transitions, the structure of the gamma phase has been determined at 583 K using a single-crystal analysis. Both structural and nonlinear optical measurements indicate a beta-gamma first-order phase transition temperature that is close to 563 K. The structure of the gamma phase is monoclinic (C2) and does not differ essentially from the alpha phase (C2). Comparison of the alpha and gamma structures shows that the main atomic shifts and tiltings are connected with Te4, Te5 and Te6 pyramids.
