BaGe3 crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of distorted face and corner-sharing BaGe12 cuboctahedra. Ge(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1) and six equivalent Ge(1) atoms.
BaGe3 crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of distorted face and corner-sharing BaGe12 cuboctahedra. There are six shorter (3.48 Å) and six longer (3.55 Å) Ba(1)-Ge(1) bond lengths. Ge(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1) and six equivalent Ge(1) atoms. There are two shorter (2.59 Å) and four longer (2.95 Å) Ge(1)-Ge(1) bond lengths.
