The crystal structure described by K2CdO2 is Ilmenite-like structured and crystallizes in the orthorhombic Pbcn space group. K(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 to four equivalent K(1) and two equivalent Cd(1) atoms to form a mixture of distorted corner, edge, and face-sharing OK4Cd2 octahedra. The corner-sharing octahedral tilt angles range from 48-71°. is represented by the Crystallographic Information File (CIF) [CIF]
