The material described by SmGe2 crystallizes in the tetragonal I4_1/amd space group. Sm(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of edge and face-sharing SmGe12 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Ge(1) atoms. is represented by the CIF card [CIF]
