Hf3I is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a distorted see-saw-like geometry to four equivalent I(1) atoms. I(1) is bonded to twelve equivalent Hf(1) atoms to form a mixture of face and corner-sharing IHf12 cuboctahedra.
Hf3I is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a distorted see-saw-like geometry to four equivalent I(1) atoms. There are two shorter (3.13 Å) and two longer (3.25 Å) Hf(1)-I(1) bond lengths. I(1) is bonded to twelve equivalent Hf(1) atoms to form a mixture of face and corner-sharing IHf12 cuboctahedra.
