Materials Data on EuWO3 by Materials Project

Abstract

EuWO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Eu3+ is bonded to twelve equivalent O2- atoms to form EuO12 cuboctahedra that share corners with twelve equivalent EuO12 cuboctahedra, faces with six equivalent EuO12 cuboctahedra, and faces with eight equivalent WO6 octahedra. All Eu–O bond lengths are 2.90 Å. W3+ is bonded to six equivalent O2- atoms to form WO6 octahedra that share corners with six equivalent WO6 octahedra and faces with eight equivalent EuO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All W–O bond lengths are 2.05 Å. O2- is bonded to four equivalent Eu3+ and two equivalent W3+ atoms to form a mixture of distorted corner, edge, and face-sharing OEu4W2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
