Materials Data on Ba3SrO4 by Materials Project
Ba3SrO4 is Caswellsilverite-like structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ba2+ is bonded to six O2- atoms to form BaO6 octahedra that share corners with six equivalent BaO6 octahedra, edges with four equivalent SrO6 octahedra, and edges with eight equivalent BaO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ba–O bond lengths are 2.77 Å. Sr2+ is bonded to six O2- atoms to form SrO6 octahedra that share corners with six equivalent SrO6 octahedra and edges with twelve equivalent BaO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sr–O bond lengths are 2.77 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to six equivalent Ba2+ atoms to form OBa6 octahedra that share corners with six equivalent OBa6 octahedra and edges with twelve OBa4Sr2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to four equivalent Ba2+ and two equivalent Sr2+ atoms to form OBa4Sr2 octahedra that share corners with six equivalent OBa4Sr2 octahedra and edges with twelve OBa6 octahedra. The corner-sharing octahedral tilt angles are 0°. All O–Ba bond lengths are 2.77 Å. In the third O2- site, O2- is bonded to four equivalent Ba2+ and two equivalent Sr2+ atoms to form OBa4Sr2 octahedra that share corners with six equivalent OBa4Sr2 octahedra and edges with twelve OBa6 octahedra. The corner-sharing octahedral tilt angles are 0°. In the fourth O2- site, O2- is bonded to four equivalent Ba2+ and two equivalent Sr2+ atoms to form OBa4Sr2 octahedra that share corners with six equivalent OBa4Sr2 octahedra and edges with twelve OBa6 octahedra. The corner-sharing octahedral tilt angles are 0°.
