Ba(GaGe) crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded to six equivalent Ga(1) and six equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing BaGa6Ge6 cuboctahedra. In the second Ba site, Ba(2) is bonded to six equivalent Ga(1) and six equivalent Ge(1) atoms to form a mixture of distorted edge and face-sharing BaGa6Ge6 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to three equivalent Ba(1), three equivalent Ba(2), and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Ba(1), three equivalent Ba(2), and three equivalent Ga(1) atoms.
