UPb2 crystallizes in the tetragonal I4_1/amd space group. U(1) is bonded to six equivalent Pb(1) atoms to form distorted edge-sharing UPb6 octahedra. Pb(1) is bonded in a 3-coordinate geometry to three equivalent U(1) atoms.
UPb2 crystallizes in the tetragonal I4_1/amd space group. U(1) is bonded to six equivalent Pb(1) atoms to form distorted edge-sharing UPb6 octahedra. There are four shorter (3.44 Å) and two longer (3.48 Å) U(1)-Pb(1) bond lengths. Pb(1) is bonded in a 3-coordinate geometry to three equivalent U(1) atoms.
