Materials Data on Y(WO2)2 by Materials Project
Y(WO2)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Y3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Y–O bond distances ranging from 2.34–2.52 Å. There are two inequivalent W+2.50+ sites. In the first W+2.50+ site, W+2.50+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.06 Å) and two longer (2.07 Å) W–O bond lengths. In the second W+2.50+ site, W+2.50+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are two shorter (2.17 Å) and two longer (2.18 Å) W–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Y3+ and two W+2.50+ atoms to form a mixture of edge and corner-sharing OY2W2 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Y3+ and two W+2.50+ atoms to form a mixture of edge and corner-sharing OY2W2 tetrahedra.
