Cr Cd Cd Cd Rh
CrRhCd3 is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Cr(1) is bonded to six equivalent Cd(1) atoms to form corner-sharing CrCd6 octahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.39 Å) and three longer (2.66 Å) Cr(1)-Cd(1) bond lengths. Rh(1) is bonded in a 9-coordinate geometry to nine equivalent Cd(1) atoms. There are three shorter (3.38 Å) and six longer (3.58 Å) Rh(1)-Cd(1) bond lengths. Cd(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and three equivalent Rh(1) atoms.
