Materials Data on Y6WO12 by Materials Project
Y6WO12 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.21–2.74 Å. W6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All W–O bond lengths are 1.97 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Y3+ and one W6+ atom. In the second O2- site, O2- is bonded to four equivalent Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra.
