Ce2RuCo3Ge4 crystallizes in the tetragonal P-4m2 space group. Ce(1) is bonded in a 16-coordinate geometry to two equivalent Ru(1), two equivalent Co(1), two equivalent Co(2), two equivalent Co(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. Ru(1) is bonded to four equivalent Ce(1), four equivalent Co(2), and four equivalent Ge(1) atoms to form distorted RuCe4Co4Ge4 cuboctahedra that share corners with four equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, faces with four equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, and faces with four equivalent Co(2)Ce4Ge4Ru4 cuboctahedra. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 4-coordinate geometry to four equivalent Ce(1) and four equivalent Ge(2) atoms. In the second Co site, Co(2) 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 Co(2)Ce4Ge4Ru4 cuboctahedra, faces with four equivalent Ru(1)Ce4Co4Ge4 cuboctahedra, and faces with four equivalent Co(2)Ce4Ge4Ru4 cuboctahedra. In the third Co site, Co(3) is bonded in a 4-coordinate geometry to four equivalent Ce(1) and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Ru(1), two equivalent Co(2), and one Ge(2) atom.
