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°.
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. There is one shorter (2.80 Å) and one longer (3.02 Å) Rb(1)-O(1) bond length. There are a spread of Rb(1)-O(2) bond distances ranging from 2.83-3.15 Å. Pb(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted edge-sharing PbO5 trigonal bipyramids. The Pb(1)-O(1) bond length is 2.04 Å. There are two shorter (2.19 Å) and two longer (2.20 Å) Pb(1)-O(2) bond lengths. 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.
