PaSb3 crystallizes in the hexagonal P6_3/mmc space group. Pa(1) is bonded to twelve equivalent Sb(1) atoms to form a mixture of corner and face-sharing PaSb12 cuboctahedra. Sb(1) is bonded in a 8-coordinate geometry to four equivalent Pa(1) and four equivalent Sb(1) atoms.
PaSb3 crystallizes in the hexagonal P6_3/mmc space group. Pa(1) is bonded to twelve equivalent Sb(1) atoms to form a mixture of corner and face-sharing PaSb12 cuboctahedra. There are six shorter (3.18 Å) and six longer (3.46 Å) Pa(1)-Sb(1) bond lengths. Sb(1) is bonded in a 8-coordinate geometry to four equivalent Pa(1) and four equivalent Sb(1) atoms. There are two shorter (3.05 Å) and two longer (3.30 Å) Sb(1)-Sb(1) bond lengths.
