Materials Data on HoWO5 by Materials Project
HoWO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ho is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ho–O bond distances ranging from 2.27–2.45 Å. W is bonded in a distorted trigonal bipyramidal geometry to five O atoms. There are a spread of W–O bond distances ranging from 1.80–2.19 Å. There are five inequivalent O sites. In the first O site, O is bonded in a trigonal non-coplanar geometry to two equivalent Ho and one W atom. In the second O site, O is bonded in a distorted trigonal planar geometry to two equivalent Ho and one W atom. In the third O site, O is bonded in a distorted trigonal planar geometry to two equivalent Ho and one W atom. In the fourth O site, O is bonded in a linear geometry to one Ho and one W atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Ho and one W atom.
