Materials Data on SrHgO3 by Materials Project
SrHgO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sr is bonded to twelve equivalent O atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, and faces with eight equivalent HgO6 octahedra. All Sr–O bond lengths are 3.00 Å. Hg is bonded to six equivalent O atoms to form HgO6 octahedra that share corners with six equivalent HgO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Hg–O bond lengths are 2.12 Å. O is bonded to four equivalent Sr and two equivalent Hg atoms to form a mixture of distorted corner, edge, and face-sharing OSr4Hg2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
