Materials Data on CrGeSbO6 by Materials Project
CrGeSbO6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2nm space group. The structure is three-dimensional. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with four equivalent GeO6 octahedra, corners with four equivalent SbO6 octahedra, an edgeedge with one GeO6 octahedra, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedra tilt angles range from 48–53°. There are a spread of Cr–O bond distances ranging from 2.00–2.02 Å. Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with four equivalent CrO6 octahedra, corners with four equivalent SbO6 octahedra, an edgeedge with one CrO6 octahedra, and an edgeedge with one SbO6 octahedra. The corner-sharing octahedra tilt angles range from 48–49°. There are a spread of Ge–O bond distances ranging from 1.91–1.95 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with four equivalent CrO6 octahedra, corners with four equivalent GeO6 octahedra, an edgeedge with one CrO6 octahedra, and an edgeedge with one GeO6 octahedra. The corner-sharing octahedra tilt angles range from 48–53°. There are four shorter (2.00 Å) and two longer (2.02 Å) Sb–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cr3+, one Ge4+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cr3+, one Ge4+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cr3+, one Ge4+, and one Sb5+ atom.
