CeFe2Ge2 crystallizes in the tetragonal I4/mmm space group. Ce(1) is bonded in a 16-coordinate geometry to eight equivalent Fe(1) and eight equivalent Ge(1) atoms. Fe(1) is bonded to four equivalent Ce(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge, corner, and face-sharing FeCe4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Fe(1), and one Ge(1) atom.
