Materials Data on Th3O by Materials Project
Th3O crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Th sites. In the first Th site, Th is bonded in a 12-coordinate geometry to eight Th and four equivalent O atoms. There are four shorter (3.19 Å) and four longer (3.39 Å) Th–Th bond lengths. All Th–O bond lengths are 3.39 Å. In the second Th site, Th is bonded in a square co-planar geometry to eight equivalent Th and four equivalent O atoms. All Th–O bond lengths are 3.19 Å. O is bonded to twelve Th atoms to form a mixture of edge, corner, and face-sharing OTh12 cuboctahedra.
