NaTl3 crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to twelve equivalent Tl(1) atoms to form a mixture of corner and face-sharing NaTl12 cuboctahedra. Tl(1) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent Tl(1) atoms.
NaTl3 crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to twelve equivalent Tl(1) atoms to form a mixture of corner and face-sharing NaTl12 cuboctahedra. There are six shorter (3.38 Å) and six longer (3.66 Å) Na(1)-Tl(1) bond lengths. Tl(1) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent Tl(1) atoms. All Tl(1)-Tl(1) bond lengths are 3.34 Å.
