Materials Data on Sr2TiMoO6 by Materials Project

Abstract

Sr2TiMoO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four equivalent TiO6 octahedra, and faces with four equivalent MoO6 octahedra. All Sr–O bond lengths are 2.83 Å. Ti4+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with six equivalent MoO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ti–O bond lengths are 1.97 Å. Mo4+ is bonded to six equivalent O2- atoms to form MoO6 octahedra that share corners with six equivalent TiO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Mo–O bond lengths are 2.04 Å. O2- is bonded in a distorted linear geometry to four equivalent Sr2+, one Ti4+, and one Mo4+ atom.
