Materials Data on Sm2Th3O9 by Materials Project
Abstract
Th3Sm2O9 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Th4+ sites. In the first Th4+ site, Th4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Th–O bond distances ranging from 2.35–2.53 Å. In the second Th4+ site, Th4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Th–O bond distances ranging from 2.38–2.48 Å. In the third Th4+ site, Th4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Th–O bond distances ranging from 2.35–2.53 Å. There are two inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sm–O bond distances ranging from 2.24–2.54 Å. In the second Sm3+ site, Sm3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sm–O bond distances ranging from 2.24–2.53 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to four Th4+ atoms to form a mixture of corner and edge-sharing OTh4 tetrahedra. In the second O2- site,more »
