The structure described by Rb2PrO3 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Pr(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing PrO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Rb(1) and two equivalent Pr(1) atoms to form a mixture of distorted corner, edge, and face-sharing ORb4Pr2 octahedra. The corner-sharing octahedral tilt angles range from 38-53°. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Pr(1) atom. is represented by the CIF file [CIF]
