Materials Data on Rb2CdO2 by Materials Project
Rb2CdO2 is Ilmenite-like structured and crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Rb1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are a spread of Rb–O bond distances ranging from 2.82–3.06 Å. Cd2+ is bonded to four equivalent O2- atoms to form distorted edge-sharing CdO4 trigonal pyramids. There are two shorter (2.23 Å) and two longer (2.33 Å) Cd–O bond lengths. O2- is bonded in a 6-coordinate geometry to four equivalent Rb1+ and two equivalent Cd2+ atoms.
