Materials Data on ErVO4 by Materials Project

ErVO4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Er3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.34 Å) and four longer (2.38 Å) Er–O bond lengths. V5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All V–O bond lengths are 1.76 Å. O2- is bonded in a 3-coordinate geometry to two equivalent Er3+ and one V5+ atom.

Materials Data on ErVO3 by Materials Project

ErVO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Er3+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Er–O bond distances ranging from 2.22–2.71 Å. V3+ is bonded to six O2- atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedra tilt angles range from 38–41°. There are a spread of V–O bond distances ranging from 2.00–2.11 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Er3+ and two equivalent V3+ atoms. In the second O2- site, O2- is bonded to two equivalent Er3+ and two equivalent V3+ atoms to form distorted corner-sharing OEr2V2 trigonal pyramids.

Materials Data on ErVO2 by Materials Project

ErVO2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Er is bonded to six equivalent O atoms to form edge-sharing ErO6 octahedra. There are four shorter (2.31 Å) and two longer (2.32 Å) Er–O bond lengths. V is bonded in a square co-planar geometry to four equivalent O atoms. All V–O bond lengths are 2.20 Å. O is bonded to three equivalent Er and two equivalent V atoms to form a mixture of distorted corner and edge-sharing OEr3V2 trigonal bipyramids.
