In the second Er3+ site, Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with six MoO6 octahedra, a faceface with one SrO12 cuboctahedra, and faces with seven BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–10°. There are a spread of Er–O bond distances ranging from 2.21–2.23 Å. There are two inequivalent Mo5+ sites. In the first Mo5+ site, Mo5+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six ErO6 octahedra, a faceface with one SrO12 cuboctahedra, and faces with seven BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–10°. There are a spread of Mo–O bond distances ranging from 1.95–2.04 Å. In the second Mo5+ site, Mo5+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six ErO6 octahedra, faces with three equivalent SrO12 cuboctahedra, and faces with five BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–10°. There are a spread of Mo–O bond distances ranging from 1.95–2.05 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Sr2+, one Er3+, and one Mo5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Sr2+, one Er3+, and one Mo5+ atom. In the third O2- site, O2- is bonded in a distorted linear geometry to four Ba2+, one Er3+, and one Mo5+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to two Ba2+, two equivalent Sr2+, one Er3+, and one Mo5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to four Ba2+, one Er3+, and one Mo5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Ba2+, two equivalent Sr2+, one Er3+, and one Mo5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to three Ba2+, one Sr2+, one Er3+, and one Mo5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to three Ba2+, one Sr2+, one Er3+, and one Mo5+ atom.
