PrAsO4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. Pr(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a 3-coordinate geometry to two equivalent Pr(1) and one As(1) atom.
PrAsO4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. Pr(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are four shorter (2.47 Å) and four longer (2.51 Å) Pr(1)-O(1) bond lengths. As(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. All As(1)-O(1) bond lengths are 1.70 Å. O(1) is bonded in a 3-coordinate geometry to two equivalent Pr(1) and one As(1) atom.
