Abstract

Er5(ReO6)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to seven O2- atoms to form distorted ErO7 pentagonal bipyramids that share corners with two equivalent ErO6 octahedra, an edgeedge with one ErO6 octahedra, edges with two equivalent ReO6 octahedra, and edges with two equivalent ErO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 56°. There are a spread of Er–O bond distances ranging from 2.26–2.41 Å. In the second Er3+ site, Er3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Er–O bond distances ranging from 2.25–2.48 Å. In the third Er3+ site, Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with four equivalent ReO6 octahedra, corners with four equivalent ErO7 pentagonal bipyramids, and edges with two equivalent ErO7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 38°. There are two shorter (2.19 Å) and four longer (2.30 Å) Er–O bond lengths. Re+4.50+ is bonded to six O2- atoms to form ReO6 octahedra that share corners with two equivalent ErO6 octahedra, edges with two equivalent ReO6 octahedra, and edges with twomore »« less
