Abstract
The evolution of the crystal structure of the title compound is monitored from room temperature to 1250 °C by powder neutron and synchrotron XRD. At 50 °C Sr2YTaO6 crystallizes with a monoclinic superstructure in the space group P21/n, at 1000 °C in the tetragonal space group I4/m, and at 1200 °C in the cubic space group Fm equation image m. The tilting of the octahedra which exists in the room temperature structure is progressively lost upon heating. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
