Materials Data on ThGeO4 by Materials Project

ThGeO4 is Zircon structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Th4+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.37 Å) and four longer (2.50 Å) Th–O bond lengths. Ge4+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Ge–O bond lengths are 1.78 Å. O2- is bonded in a 3-coordinate geometry to two equivalent Th4+ and one Ge4+ atom.

Materials Data on ThGeO2 by Materials Project

ThO2Ge crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional and consists of eight germanium molecules and one ThO2 framework. In the ThO2 framework, Th is bonded to six equivalent O atoms to form distorted edge-sharing ThO6 octahedra. There are a spread of Th–O bond distances ranging from 2.35–2.41 Å. O is bonded in a distorted trigonal non-coplanar geometry to three equivalent Th atoms.

Materials Data on Th(GeO)2 by Materials Project

Th(GeO)2 crystallizes in the tetragonal I4_1/amd space group. The structure is zero-dimensional and consists of eight Th(GeO)2 clusters. Th is bonded in a linear geometry to two equivalent O atoms. Both Th–O bond lengths are 2.14 Å. Ge is bonded in a distorted single-bond geometry to one O atom. The Ge–O bond length is 1.82 Å. O is bonded in a bent 150 degrees geometry to one Th and one Ge atom.
