The material structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
