Rb Cd Cd Cd Co
RbCoCd3 crystallizes in the trigonal R3m space group. Rb(1) is bonded in a 12-coordinate geometry to twelve equivalent Cd(1) atoms. There are a spread of Rb(1)-Cd(1) bond distances ranging from 3.07-4.23 Å. Co(1) is bonded to six equivalent Cd(1) atoms to form corner-sharing CoCd6 octahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.17 Å) and three longer (2.99 Å) Co(1)-Cd(1) bond lengths. Cd(1) is bonded in a 1-coordinate geometry to four equivalent Rb(1) and two equivalent Co(1) atoms.
