Materials Data on YV(SeO4)2 by Materials Project
YV(SeO4)2 crystallizes in the orthorhombic Aem2 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 2.34–2.45 Å. V5+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.64–2.41 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.73 Å) and two longer (1.76 Å) Se–O bond length. In the second Se4+ site, Se4+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is two shorter (1.73 Å) and one longer (1.76 Å) Se–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one V5+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent V5+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V5+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Y3+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Y3+ and one Se4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Y3+ and one Se4+ atom.
