Pb2CdUO6 crystallizes in the monoclinic P2_1/c space group. U(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form UO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-34°. Cd(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CdO6 octahedra that share corners with six equivalent U(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-34°. Pb(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one U(1), one Cd(1), and one Pb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one U(1), one Cd(1), and one Pb(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one U(1), one Cd(1), and two equivalent Pb(1) atoms.
