The material structure described by LaGe2 is hexagonal omega structure-like structured and crystallizes in the tetragonal I4_1/amd space group. La(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of edge and face-sharing LaGe12 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
