The material structure described by Rb2U3(TeO7)2 crystallizes in the triclinic P-1 space group. Rb(1) is bonded in a 6-coordinate geometry to one O(3), one O(5), two equivalent O(6), and two equivalent O(7) atoms. There are two inequivalent U sites. In the first U site, U(1) is bonded to two equivalent O(1), two equivalent O(4), and two equivalent O(7) atoms to form a mixture of distorted edge and corner-sharing UO6 octahedra. In the second U site, U(2) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms to form distorted UO7 pentagonal bipyramids that share  a cornercorner with one U(1)O6 octahedra,  an edgeedge with one U(1)O6 octahedra, and  an edgeedge with one U(2)O7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 47°. Te(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one U(1), one U(2), and one Te(1) atom. In the second O site, O(2) is bonded in a linear geometry to one U(2) and one Te(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Rb(1), one U(2), and two equivalent Te(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one U(1) and two equivalent U(2) atoms. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Rb(1) and one U(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one U(2) atom. In the seventh O site, O(7) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one U(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
