PrBiO4 crystallizes in the orthorhombic Pnna space group. Pr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pr(1) and two equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OPr2Bi2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Pr(1) and one Bi(1) atom.
PrBiO4 crystallizes in the orthorhombic Pnna space group. Pr(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.45 Å) and two longer (2.56 Å) Pr(1)-O(1) bond lengths. There are two shorter (2.43 Å) and two longer (2.49 Å) Pr(1)-O(2) bond lengths. Bi(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Both Bi(1)-O(2) bond lengths are 2.04 Å. There are two shorter (2.13 Å) and two longer (2.33 Å) Bi(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pr(1) and two equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OPr2Bi2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Pr(1) and one Bi(1) atom.
