NdRh2Ge2 crystallizes in the tetragonal I4/mmm space group. Nd(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 Nd(1) and four equivalent Ge(1) atoms to form a mixture of distorted corner, face, and edge-sharing RhNd4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1), four equivalent Rh(1), and one Ge(1) atom.
