The material structure described by Cs2Pb2O3 crystallizes in the cubic I2_13 space group. Cs(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 Cs(1) and two equivalent Pb(1) atoms to form a mixture of distorted corner, edge, and face-sharing OCs4Pb2 octahedra. The corner-sharing octahedral tilt angles range from 56-60°. is represented by the CIF file [CIF]
