Bi2UO6 crystallizes in the trigonal P-3m1 space group. U(1) is bonded to two equivalent O(3) and six equivalent O(2) atoms to form distorted edge-sharing UO8 hexagonal bipyramids. Bi(1) is bonded in a 7-coordinate geometry to three equivalent O(3) and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent U(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one U(1) and three equivalent Bi(1) atoms.
Bi2UO6 crystallizes in the trigonal P-3m1 space group. U(1) is bonded to two equivalent O(3) and six equivalent O(2) atoms to form distorted edge-sharing UO8 hexagonal bipyramids. Both U(1)-O(3) bond lengths are 2.01 Å. All U(1)-O(2) bond lengths are 2.28 Å. Bi(1) is bonded in a 7-coordinate geometry to three equivalent O(3) and four equivalent O(1) atoms. All Bi(1)-O(3) bond lengths are 2.57 Å. There is one shorter (2.28 Å) and three longer (2.36 Å) Bi(1)-O(1) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Bi(1) atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent U(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one U(1) and three equivalent Bi(1) atoms.
