Materials Data on YV(TeO4)2 by Materials Project
YV(TeO4)2 crystallizes in the orthorhombic Cmce 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 2.29–2.50 Å. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.65–2.45 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is two shorter (1.92 Å) and one longer (1.93 Å) Te–O bond length. In the second Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is one shorter (1.88 Å) and two longer (1.95 Å) Te–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Y3+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Y3+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Y3+ and one Te4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one V5+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent V5+ atoms.
