U is Hg_xSn structured and crystallizes in the hexagonal P6/mmm space group. U(1) is bonded to eight equivalent U(1) atoms to form a mixture of corner and edge-sharing UU8 hexagonal bipyramids.
U is Hg_xSn structured and crystallizes in the hexagonal P6/mmm space group. U(1) is bonded to eight equivalent U(1) atoms to form a mixture of corner and edge-sharing UU8 hexagonal bipyramids. There are two shorter (2.78 Å) and six longer (2.80 Å) U(1)-U(1) bond lengths.
