Materials Data on Sr2VMoO6 by Materials Project
Sr2VMoO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four equivalent VO6 octahedra, and faces with four equivalent MoO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.73–2.90 Å. V2+ is bonded to six O2- atoms to form VO6 octahedra that share corners with two equivalent MoO6 octahedra, corners with four equivalent VO6 octahedra, and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is two shorter (1.89 Å) and four longer (2.02 Å) V–O bond length. Mo6+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with two equivalent VO6 octahedra, corners with four equivalent MoO6 octahedra, and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.02 Å) and two longer (2.03 Å) Mo–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+, one V2+, and one Mo6+ atom. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent V2+ atoms to form a mixture of distorted edge, face, and corner-sharing OSr4V2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the third O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two equivalent Mo6+ atoms.
