The compound described by Sm2Rh3Ge crystallizes in the trigonal R-3m space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1), nine equivalent Rh(1), and three equivalent Ge(1) atoms. Rh(1) is bonded to six equivalent Sm(1), four equivalent Rh(1), and two equivalent Ge(1) atoms to form distorted RhSm6Ge2Rh4 cuboctahedra that share corners with four equivalent Ge(1)Sm6Rh6 cuboctahedra, corners with fourteen equivalent Rh(1)Sm6Ge2Rh4 cuboctahedra, edges with six equivalent Rh(1)Sm6Ge2Rh4 cuboctahedra, faces with six equivalent Ge(1)Sm6Rh6 cuboctahedra, and faces with twelve equivalent Rh(1)Sm6Ge2Rh4 cuboctahedra. Ge(1) is bonded to six equivalent Sm(1) and six equivalent Rh(1) atoms to form distorted GeSm6Rh6 cuboctahedra that share corners with six equivalent Ge(1)Sm6Rh6 cuboctahedra, corners with twelve equivalent Rh(1)Sm6Ge2Rh4 cuboctahedra, edges with six equivalent Ge(1)Sm6Rh6 cuboctahedra, and faces with eighteen equivalent Rh(1)Sm6Ge2Rh4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
