GdAlGe crystallizes in the tetragonal I4_1md space group. Gd(1) is bonded to six equivalent Al(1) and six equivalent Ge(1) atoms to form a mixture of face and edge-sharing GdAl6Ge6 cuboctahedra. Al(1) is bonded in a distorted trigonal planar geometry to six equivalent Gd(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a distorted trigonal planar geometry to six equivalent Gd(1) and three equivalent Al(1) atoms.
GdAlGe crystallizes in the tetragonal I4_1md space group. Gd(1) is bonded to six equivalent Al(1) and six equivalent Ge(1) atoms to form a mixture of face and edge-sharing GdAl6Ge6 cuboctahedra. There are four shorter (3.21 Å) and two longer (3.22 Å) Gd(1)-Al(1) bond lengths. There are four shorter (3.20 Å) and two longer (3.25 Å) Gd(1)-Ge(1) bond lengths.
