Materials Data on YbPO4 by Materials Project
YbPO4 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. Yb3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.42 Å) and four longer (2.44 Å) Yb–O bond lengths. P5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All P–O bond lengths are 1.55 Å. O2- is bonded in a distorted single-bond geometry to two equivalent Yb3+ and one P5+ atom.
