Materials Data on Eu3ReO8 by Materials Project
Eu3ReO8 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are three inequivalent Eu3+ sites. In the first Eu3+ site, Eu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Eu–O bond distances ranging from 2.30–2.58 Å. In the second Eu3+ site, Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.44–2.78 Å. In the third Eu3+ site, Eu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Eu–O bond distances ranging from 2.30–2.53 Å. Re7+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Re–O bond distances ranging from 1.82–2.02 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Eu3+ and one Re7+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Eu3+ and one Re7+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Eu3+ and one Re7+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two Eu3+ and one Re7+ atom. In the fifth O2- site, O2- is bonded to four Eu3+ atoms to form a mixture of distorted edge and corner-sharing OEu4 tetrahedra. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Eu3+ and one Re7+ atom.
