Abstract

BaHo2ZnO5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.74–3.32 Å. There are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to seven O2- atoms to form distorted HoO7 pentagonal bipyramids that share corners with five equivalent ZnO5 trigonal bipyramids, edges with five HoO7 pentagonal bipyramids, an edgeedge with one ZnO5 trigonal bipyramid, and a faceface with one HoO7 pentagonal bipyramid. There are a spread of Ho–O bond distances ranging from 2.30–2.37 Å. In the second Ho3+ site, Ho3+ is bonded to seven O2- atoms to form distorted HoO7 pentagonal bipyramids that share corners with four equivalent HoO7 pentagonal bipyramids, edges with three equivalent HoO7 pentagonal bipyramids, edges with two equivalent ZnO5 trigonal bipyramids, a faceface with one HoO7 pentagonal bipyramid, and a faceface with one ZnO5 trigonal bipyramid. There are a spread of Ho–O bond distances ranging from 2.30–2.39 Å.
