The crystal structure described by CaCd(CO3)2 is Calcite-derived structured and crystallizes in the trigonal R-3 space group. Ca(1) is bonded to six equivalent O(1) atoms to form CaO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 62°. Cd(1) is bonded to six equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Ca(1)O6 octahedra. The corner-sharing octahedral tilt angles are 62°. C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to one Ca(1), one Cd(1), and one C(1) atom. is represented by the CIF card [CIF]
