The material structure described by Rb2PbO3 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. Pb(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing PbO5 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 Pb(1) atoms to form a mixture of distorted corner, face, and edge-sharing ORb4Pb2 octahedra. The corner-sharing octahedral tilt angles range from 37-53°. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Pb(1) atom. is represented by the CIF file [CIF]
