HoMn2Ge2 crystallizes in the tetragonal I4/mmm space group. Ho(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. Mn(1) is bonded to four equivalent Ge(1) atoms to form a mixture of corner and edge-sharing MnGe4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1), four equivalent Mn(1), and one Ge(1) atom.
