The material described by Sm2Ru3Ge crystallizes in the trigonal R-3m space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1), nine equivalent Ru(1), and three equivalent Ge(1) atoms. Ru(1) is bonded to six equivalent Sm(1), four equivalent Ru(1), and two equivalent Ge(1) atoms to form distorted RuSm6Ge2Ru4 cuboctahedra that share corners with four equivalent Ge(1)Sm6Ru6 cuboctahedra, corners with fourteen equivalent Ru(1)Sm6Ge2Ru4 cuboctahedra, edges with six equivalent Ru(1)Sm6Ge2Ru4 cuboctahedra, faces with six equivalent Ge(1)Sm6Ru6 cuboctahedra, and faces with twelve equivalent Ru(1)Sm6Ge2Ru4 cuboctahedra. Ge(1) is bonded to six equivalent Sm(1) and six equivalent Ru(1) atoms to form GeSm6Ru6 cuboctahedra that share corners with six equivalent Ge(1)Sm6Ru6 cuboctahedra, corners with twelve equivalent Ru(1)Sm6Ge2Ru4 cuboctahedra, edges with six equivalent Ge(1)Sm6Ru6 cuboctahedra, and faces with eighteen equivalent Ru(1)Sm6Ge2Ru4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
