Materials Data on SrEuO2 by Materials Project

Abstract

SrEuO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent O2- atoms to form SrO6 octahedra that share corners with six equivalent EuO6 octahedra, edges with six equivalent SrO6 octahedra, and edges with six equivalent EuO6 octahedra. The corner-sharing octahedral tilt angles are 1°. All Sr–O bond lengths are 2.60 Å. Eu2+ is bonded to six equivalent O2- atoms to form EuO6 octahedra that share corners with six equivalent SrO6 octahedra, edges with six equivalent SrO6 octahedra, and edges with six equivalent EuO6 octahedra. The corner-sharing octahedral tilt angles are 1°. All Eu–O bond lengths are 2.55 Å. O2- is bonded to three equivalent Sr2+ and three equivalent Eu2+ atoms to form a mixture of edge and corner-sharing OSr3Eu3 octahedra. The corner-sharing octahedral tilt angles are 0°.
