The crystal structure described by UPbTe2O8 crystallizes in the monoclinic P2_1/c space group. U(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(7), two equivalent O(5), and two equivalent O(8) atoms. Pb(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), one O(4), one O(6), and two equivalent O(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 3-coordinate geometry to one O(2), one O(4), one O(6), and one O(7) atom. In the second Te site, Te(2) is bonded in a rectangular see-saw-like geometry to one O(2), one O(5), one O(6), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one U(1) and two equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Pb(1), one Te(1), and one Te(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one U(1) and one Pb(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one Pb(1) and one Te(1) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to two equivalent U(1) and one Te(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Pb(1), one Te(1), and one Te(2) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one U(1) and one Te(1) atom. In the eighth O site, O(8) is bonded in a 3-coordinate geometry to two equivalent U(1) and one Te(2) atom. is represented by the CIF file [CIF]
