Rb2CdO2 crystallizes in the orthorhombic Pbcn space group. Rb(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. Cd(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing CdO4 trigonal pyramids. O(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1) and two equivalent Cd(1) atoms.
Rb2CdO2 crystallizes in the orthorhombic Pbcn space group. Rb(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are a spread of Rb(1)-O(1) bond distances ranging from 2.78-3.01 Å. Cd(1) is bonded to four equivalent O(1) atoms to form distorted edge-sharing CdO4 trigonal pyramids. There are two shorter (2.20 Å) and two longer (2.29 Å) Cd(1)-O(1) bond lengths. O(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1) and two equivalent Cd(1) atoms.
