Materials Data on ThSb2 by Materials Project
ThSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Th4+ is bonded in a 9-coordinate geometry to nine Sb2- atoms. There are a spread of Th–Sb bond distances ranging from 3.22–3.37 Å. There are two inequivalent Sb2- sites. In the first Sb2- site, Sb2- is bonded in a 8-coordinate geometry to four equivalent Th4+ and four equivalent Sb2- atoms. All Sb–Sb bond lengths are 3.12 Å. In the second Sb2- site, Sb2- is bonded to five equivalent Th4+ atoms to form a mixture of distorted corner and edge-sharing SbTh5 trigonal bipyramids.
