RhCdSi crystallizes in the trigonal R3m space group. Rh(1) is bonded in a single-bond geometry to one Cd(1) and three equivalent Si(1) atoms. The Rh(1)-Cd(1) bond length is 0.34 Å. All Rh(1)-Si(1) bond lengths are 2.71 Å. Cd(1) is bonded in a single-bond geometry to one Rh(1) and three equivalent Si(1) atoms. All Cd(1)-Si(1) bond lengths are 3.07 Å. Si(1) is bonded to three equivalent Rh(1) and three equivalent Cd(1) atoms to form distorted edge-sharing SiCd3Rh3 octahedra.
