Abstract

Ba3Er2MoO9 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, faces with three equivalent MoO6 octahedra, and faces with five equivalent ErO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.80–3.22 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with two equivalent MoO6 octahedra, and faces with six equivalent ErO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.84–3.23 Å. Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with three equivalent ErO6 octahedra, corners with three equivalent MoO6 octahedra, and faces with eight BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–14°. There are three shorter (2.15 Å) and three longer (2.34 Å) Er–O bond lengths. Mo6+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with six equivalent ErO6 octahedra and facesmore »« less
