The compound described by CeRuCoGe2 crystallizes in the tetragonal I-4m2 space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1), four equivalent Co(1), and eight equivalent Ge(1) atoms. Ru(1) is bonded to four equivalent Ce(1), four equivalent Co(1), and four equivalent Ge(1) atoms to form distorted RuCe4Co4Ge4 cuboctahedra that share corners with four equivalent Co(1)Ce4Ge4Ru4 cuboctahedra, corners with twelve equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, edges with two equivalent Co(1)Ce4Ge4Ru4 cuboctahedra, faces with four equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, and faces with four equivalent Co(1)Ce4Ge4Ru4 cuboctahedra. Co(1) is bonded to four equivalent Ce(1), four equivalent Ru(1), and four equivalent Ge(1) atoms to form distorted CoCe4Ge4Ru4 cuboctahedra that share corners with four equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, corners with twelve equivalent Co(1)Ce4Ge4Ru4 cuboctahedra, edges with two equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, faces with four equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, and faces with four equivalent Co(1)Ce4Ge4Ru4 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Ru(1), two equivalent Co(1), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
