Title: Materials Data on Al2GeO6 by Materials Project

Abstract

Al2GeO6 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Al is bonded to six O atoms to form AlO6 octahedra that share corners with two equivalent AlO6 octahedra, corners with four equivalent GeO4 tetrahedra, and edges with two equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 25°. There are a spread of Al–O bond distances ranging from 1.84–1.97 Å. Ge is bonded to four O atoms to form GeO4 tetrahedra that share corners with eight equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 51–54°. There are a spread of Ge–O bond distances ranging from 1.77–1.79 Å. There are four inequivalent O sites. In the first O site, O is bonded in a trigonal planar geometry to two equivalent Al and one Ge atom. In the second O site, O is bonded in a distorted trigonal planar geometry to two equivalent Al and one Ge atom. In the third O site, O is bonded in a trigonal planar geometry to two equivalent Al and one Ge atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to two equivalent Al atoms.
