The material described by Rb2Pb2O3 crystallizes in the cubic I2_13 space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Pb(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. O(1) is bonded to four equivalent Rb(1) and two equivalent Pb(1) atoms to form a mixture of distorted face, corner, and edge-sharing ORb4Pb2 octahedra. The corner-sharing octahedral tilt angles range from 50-61°. is represented by the CIF card [CIF]
