Abstract

Th4Sm6O17 crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are four 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 2.37–2.56 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 2.37–2.55 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 2.37–2.84 Å. In the fourth 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 2.38–2.54 Å. There are six inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sm–O bond distances ranging from 2.36–2.61 Å. In the second Sm3+ site, Sm3+ is bonded to five O2- atoms to form corner-sharing SmO5 trigonal bipyramids. There are a spread of Sm–O bond distances ranging from 2.22–2.39 Å.

In the seventh O2- site, O2- is bonded to four Th4+ atoms to form a mixture of edge and corner-sharing OTh4 tetrahedra. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Th4+ and three equivalent Sm3+ atoms. In the ninth O2- site, O2- is bonded to four Sm3+ atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra. In the tenth O2- site, O2- is bonded in a 4-coordinate geometry to four Sm3+ atoms. In the eleventh O2- site, O2- is bonded to four Sm3+ atoms to form a mixture of distorted edge and corner-sharing OSm4 tetrahedra. In the twelfth O2- site, O2- is bonded to four Sm3+ atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra. In the thirteenth O2- site, O2- is bonded in a 4-coordinate geometry to four Sm3+ atoms. In the fourteenth O2- site, O2- is bonded to four Sm3+ atoms to form a mixture of distorted edge and corner-sharing OSm4 tetrahedra. In the fifteenth O2- site, O2- is bonded to one Th4+ and three equivalent Sm3+ atoms to form OSm3Th tetrahedra that share corners with thirteen OTh4 tetrahedra and edges with six OSm4 tetrahedra. In the sixteenth O2- site, O2- is bonded to four Sm3+ atoms to form distorted OSm4 tetrahedra that share corners with sixteen OSm4 tetrahedra and edges with three equivalent OSm3Th tetrahedra. In the seventeenth O2- site, O2- is bonded to three equivalent Th4+ and one Sm3+ atom to form OSmTh3 tetrahedra that share corners with fifteen OTh4 tetrahedra and edges with six OSm3Th tetrahedra.« less
