YbFe2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb is bonded in a 8-coordinate geometry to eight equivalent Fe and eight equivalent Ge atoms. All Yb–Fe bond lengths are 3.31 Å. All Yb–Ge bond lengths are 3.05 Å. Fe is bonded to four equivalent Yb and four equivalent Ge atoms to form a mixture of edge, face, and corner-sharing FeYb4Ge4 tetrahedra. All Fe–Ge bond lengths are 2.38 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Yb, four equivalent Fe, and one Ge atom. The Ge–Ge bond length is 2.61 Å.
