Materials Data on Sm3ReO8 by Materials Project
Sm3ReO8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sm–O bond distances ranging from 2.31–2.63 Å. In the second Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sm–O bond distances ranging from 2.25–2.65 Å. In the third Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sm–O bond distances ranging from 2.36–2.67 Å. Re7+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Re–O bond distances ranging from 1.83–1.98 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded to four Sm3+ atoms to form a mixture of distorted edge and corner-sharing OSm4 tetrahedra. In the second O2- site, O2- is bonded to four Sm3+ atoms to form a mixture of distorted edge and corner-sharing OSm4 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Sm3+ and one Re7+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Sm3+ and one Re7+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two Sm3+ and one Re7+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to three Sm3+ and one Re7+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to three Sm3+ and one Re7+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Sm3+ and one Re7+ atom.
