The material described by Rb2PbO3 is Krennerite-derived structured and crystallizes in the orthorhombic Cmc2_1 space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Pb(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted edge-sharing PbO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Pb(1) atom. In the second O site, O(2) is bonded to four equivalent Rb(1) and two equivalent Pb(1) atoms to form a mixture of distorted edge, corner, and face-sharing ORb4Pb2 octahedra. The corner-sharing octahedral tilt angles range from 37-51°. is represented by the CIF card [CIF]
