Title: Materials Data on Al2Ge(HO3)2 by Materials Project

Abstract

Al2Ge(HO3)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four equivalent GeO4 tetrahedra and edges with three equivalent AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.86–1.96 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with eight equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 49–60°. There is two shorter (1.79 Å) and two longer (1.80 Å) Ge–O bond length. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Al3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Al3+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Al3+ and one H1+ atom.
