Y2Rh3Ge crystallizes in the trigonal R-3m space group. Y(1) is bonded in a 16-coordinate geometry to four equivalent Y(1), nine equivalent Rh(1), and three equivalent Ge(1) atoms. Rh(1) is bonded to six equivalent Y(1), four equivalent Rh(1), and two equivalent Ge(1) atoms to form distorted RhY6Ge2Rh4 cuboctahedra that share corners with four equivalent Ge(1)Y6Rh6 cuboctahedra, corners with fourteen equivalent Rh(1)Y6Ge2Rh4 cuboctahedra, edges with six equivalent Rh(1)Y6Ge2Rh4 cuboctahedra, faces with six equivalent Ge(1)Y6Rh6 cuboctahedra, and faces with twelve equivalent Rh(1)Y6Ge2Rh4 cuboctahedra. Ge(1) is bonded to six equivalent Y(1) and six equivalent Rh(1) atoms to form distorted GeY6Rh6 cuboctahedra that share corners with six equivalent Ge(1)Y6Rh6 cuboctahedra, corners with twelve equivalent Rh(1)Y6Ge2Rh4 cuboctahedra, edges with six equivalent Ge(1)Y6Rh6 cuboctahedra, and faces with eighteen equivalent Rh(1)Y6Ge2Rh4 cuboctahedra.
Y2Rh3Ge crystallizes in the trigonal R-3m space group. Y(1) is bonded in a 16-coordinate geometry to four equivalent Y(1), nine equivalent Rh(1), and three equivalent Ge(1) atoms. There is one shorter (3.06 Å) and three longer (3.34 Å) Y(1)-Y(1) bond lengths. There are three shorter (2.90 Å) and six longer (3.18 Å) Y(1)-Rh(1) bond lengths. All Y(1)-Ge(1) bond lengths are 3.25 Å. Rh(1) is bonded to six equivalent Y(1), four equivalent Rh(1), and two equivalent Ge(1) atoms to form distorted RhY6Ge2Rh4 cuboctahedra that share corners with four equivalent Ge(1)Y6Rh6 cuboctahedra, corners with fourteen equivalent Rh(1)Y6Ge2Rh4 cuboctahedra, edges with six equivalent Rh(1)Y6Ge2Rh4 cuboctahedra, faces with six equivalent Ge(1)Y6Rh6 cuboctahedra, and faces with twelve equivalent Rh(1)Y6Ge2Rh4 cuboctahedra. All Rh(1)-Rh(1) bond lengths are 2.79 Å. Both Rh(1)-Ge(1) bond lengths are 2.54 Å. Ge(1) is bonded to six equivalent Y(1) and six equivalent Rh(1) atoms to form distorted GeY6Rh6 cuboctahedra that share corners with six equivalent Ge(1)Y6Rh6 cuboctahedra, corners with twelve equivalent Rh(1)Y6Ge2Rh4 cuboctahedra, edges with six equivalent Ge(1)Y6Rh6 cuboctahedra, and faces with eighteen equivalent Rh(1)Y6Ge2Rh4 cuboctahedra.
