CeRh2Ge2 crystallizes in the tetragonal I4/mmm space group. Ce(1) is bonded in a 16-coordinate geometry to eight equivalent Rh(1) and eight equivalent Ge(1) atoms. Rh(1) is bonded to four equivalent Ce(1) and four equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing RhCe4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), four equivalent Rh(1), and one Ge(1) atom.
