The structure described by CeAlGe crystallizes in the tetragonal I4_1md space group. Ce(1) is bonded to six equivalent Al(1) and six equivalent Ge(1) atoms to form a mixture of face and edge-sharing CeAl6Ge6 cuboctahedra. Al(1) is bonded in a distorted trigonal planar geometry to six equivalent Ce(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a distorted trigonal planar geometry to six equivalent Ce(1) and three equivalent Al(1) atoms. is represented by the CIF card [CIF]
