The material described by BaGe2 is hexagonal omega structure-like structured and crystallizes in the tetragonal I4_1/amd space group. Ba(1) is bonded to twelve Ge(1,1,1) atoms to form a mixture of edge and face-sharing BaGe12 cuboctahedra. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ba(1) and three Ge(1,1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ba(1) and three Ge(1,1) atoms. In the third Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ba(1) and three Ge(1,1) atoms. In the fourth Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ba(1) and three Ge(1,1) atoms. is represented by the CIF file [CIF]
