HfH3 crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded to twelve equivalent H(1) atoms to form a mixture of distorted corner and face-sharing HfH12 cuboctahedra. H(1) is bonded in a distorted see-saw-like geometry to four equivalent Hf(1) atoms.
HfH3 crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded to twelve equivalent H(1) atoms to form a mixture of distorted corner and face-sharing HfH12 cuboctahedra. There are six shorter (2.03 Å) and six longer (2.38 Å) Hf(1)-H(1) bond lengths. H(1) is bonded in a distorted see-saw-like geometry to four equivalent Hf(1) atoms.
