The material structure described by CeCo9Ge4 crystallizes in the tetragonal I4/mcm space group. Ce(1) is bonded in a 24-coordinate geometry to eight equivalent Co(2), eight equivalent Co(3), and eight equivalent Ge(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a cuboctahedral geometry to four equivalent Co(2), four equivalent Co(3), and four equivalent Ge(1) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to two equivalent Ce(1), one Co(1), two equivalent Co(3), three equivalent Co(2), and four equivalent Ge(1) atoms. In the third Co site, Co(3) is bonded in a 4-coordinate geometry to two equivalent Ce(1), one Co(1), two equivalent Co(2), and four equivalent Ge(1) atoms. Ge(1) is bonded in a 11-coordinate geometry to two equivalent Ce(1), one Co(1), four equivalent Co(2), and four equivalent Co(3) atoms. is represented by the CIF file [CIF]
