UHg2 crystallizes in the hexagonal P6/mmm space group. U(1) is bonded in a 14-coordinate geometry to two equivalent U(1) and twelve equivalent Hg(1) atoms. Hg(1) is bonded in a distorted q6 geometry to six equivalent U(1) and five equivalent Hg(1) atoms.
UHg2 crystallizes in the hexagonal P6/mmm space group. U(1) is bonded in a 14-coordinate geometry to two equivalent U(1) and twelve equivalent Hg(1) atoms. Both U(1)-U(1) bond lengths are 3.03 Å. All U(1)-Hg(1) bond lengths are 3.36 Å. Hg(1) is bonded in a distorted q6 geometry to six equivalent U(1) and five equivalent Hg(1) atoms. There are three shorter (2.99 Å) and two longer (3.03 Å) Hg(1)-Hg(1) bond lengths.
