Tl2Ba crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded in a 12-coordinate geometry to twelve equivalent Tl(1) atoms. Tl(1) is bonded in a 10-coordinate geometry to six equivalent Ba(1) and four equivalent Tl(1) atoms.
Tl2Ba crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded in a 12-coordinate geometry to twelve equivalent Tl(1) atoms. There are six shorter (3.53 Å) and six longer (3.98 Å) Ba(1)-Tl(1) bond lengths. Tl(1) is bonded in a 10-coordinate geometry to six equivalent Ba(1) and four equivalent Tl(1) atoms. There are three shorter (3.16 Å) and one longer (3.52 Å) Tl(1)-Tl(1) bond length.
