Materials Data on Th3Ge2 by Materials Project
Th3Ge2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are two inequivalent Th sites. In the first Th site, Th is bonded in a 6-coordinate geometry to six equivalent Ge atoms. There are two shorter (3.09 Å) and four longer (3.19 Å) Th–Ge bond lengths. In the second Th site, Th is bonded in a square co-planar geometry to four equivalent Ge atoms. All Th–Ge bond lengths are 3.19 Å. Ge is bonded in a 9-coordinate geometry to eight Th and one Ge atom. The Ge–Ge bond length is 2.74 Å.
