BaTl3 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 four equivalent Ba(1) and six equivalent Tl(1) atoms.
BaTl3 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 (3.58 Å) and six longer (3.92 Å) Ba(1)-Tl(1) bond lengths. Tl(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1) and six equivalent Tl(1) atoms. There are four shorter (3.23 Å) and two longer (3.45 Å) Tl(1)-Tl(1) bond lengths.
