BaBGe2 crystallizes in the cubic F-43m space group. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent B(1), four equivalent Ge(1), and six equivalent Ge(2) atoms. B(1) is bonded to four equivalent Ba(1) atoms to form BBa4 tetrahedra that share corners with four equivalent Ge(1)Ba4Ge4 tetrahedra, corners with twelve equivalent B(1)Ba4 tetrahedra, and edges with six equivalent Ge(1)Ba4Ge4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Ba(1) and four equivalent Ge(2) atoms to form GeBa4Ge4 tetrahedra that share corners with four equivalent B(1)Ba4 tetrahedra, edges with six equivalent B(1)Ba4 tetrahedra, and edges with twelve equivalent Ge(1)Ba4Ge4 tetrahedra. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to six equivalent Ba(1) and four equivalent Ge(1) atoms.
