Description

X-ray structure investigation of Y2WO6 rhombic modification crystal with elementary cell parameters: a 5.221, b = 9.029, c = 9.915 A, sp.gr. P212121, z = 4, R 3.9 and Rw = 4.8% - is conducted. Comparison evaluation of structure variations in TR2WO6 isostructural compound series is presented. The most possible mechanisms of Y2WO6 structure rearrangement at transitions between 3-, 5-, 6- type polymorphous modifications are suggested
