Materials Data on AlSbO4 by Materials Project

Abstract

AlSbO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with eight equivalent SbO6 octahedra and edges with two equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There is two shorter (1.93 Å) and four longer (1.94 Å) Al–O bond length. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with eight equivalent AlO6 octahedra and edges with two equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There is two shorter (1.98 Å) and four longer (2.01 Å) Sb–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Al3+ and one Sb5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+ and two equivalent Sb5+ atoms.
