The crystal structure described by Rb2Cd2O3 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Cd(1) is bonded to one O(2) and three equivalent O(1) atoms to form a mixture of corner and edge-sharing CdO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and three equivalent Cd(1) atoms. In the second O site, O(2) is bonded to four equivalent Rb(1) and two equivalent Cd(1) atoms to form corner-sharing ORb4Cd2 octahedra. The corner-sharing octahedral tilt angles are 62°. is represented by the Crystallographic Information File (CIF) [CIF]
