In the first Eu+2.67+ site, Eu+2.67+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.38–2.66 Å. In the second Eu+2.67+ site, Eu+2.67+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.38–2.71 Å. In the third Eu+2.67+ site, Eu+2.67+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.39–2.75 Å. Y3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.30–2.63 Å. There are two inequivalent Mn+3.25+ sites. In the first Mn+3.25+ site, Mn+3.25+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 26–32°. There are a spread of Mn–O bond distances ranging from 1.98–2.02 Å. In the second Mn+3.25+ site, Mn+3.25+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 26–31°. There are a spread of Mn–O bond distances ranging from 1.98–2.08 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two Eu+2.67+, one Y3+, and two Mn+3.25+ atoms.
