Materials Data on AlAgO3 by Materials Project

Abstract

AgAlO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ag3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. There are two shorter (2.07 Å) and two longer (2.08 Å) Ag–O bond lengths. Al3+ is bonded to four O2- atoms to form corner-sharing AlO4 tetrahedra. There is two shorter (1.74 Å) and two longer (1.81 Å) Al–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 Ag3+ and one Al3+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Al3+ atoms.
