Ac3Br crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded in a 4-coordinate geometry to four equivalent Br(1) atoms. Br(1) is bonded to twelve equivalent Ac(1) atoms to form a mixture of corner and face-sharing BrAc12 cuboctahedra.
Ac3Br crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded in a 4-coordinate geometry to four equivalent Br(1) atoms. There are two shorter (3.68 Å) and two longer (3.97 Å) Ac(1)-Br(1) bond lengths. Br(1) is bonded to twelve equivalent Ac(1) atoms to form a mixture of corner and face-sharing BrAc12 cuboctahedra.
