PrBO3 crystallizes in the orthorhombic Pnma space group. Pr(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Pr(1) and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Pr(1) and one B(1) atom.
PrBO3 crystallizes in the orthorhombic Pnma space group. Pr(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. There is one shorter (2.43 Å) and two longer (2.70 Å) Pr(1)-O(2) bond lengths. There are a spread of Pr(1)-O(1) bond distances ranging from 2.46-2.60 Å. B(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. The B(1)-O(2) bond length is 1.37 Å. Both B(1)-O(1) bond lengths are 1.37 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Pr(1) and one B(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Pr(1) and one B(1) atom.
