The structure described by U3O10 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent U sites. In the first U site, U(1) is bonded in a 7-coordinate geometry to one O(5), one O(6), one O(7), two equivalent O(1), and two equivalent O(2) atoms. In the second U site, U(2) is bonded in a 7-coordinate geometry to one O(3), one O(4), one O(7), one O(8), one O(9), and two equivalent O(10) atoms. In the third U site, U(3) is bonded in a distorted octahedral geometry to one O(1), one O(2), one O(3), one O(5), one O(6), and one O(8) atom. There are ten inequivalent O sites. In the first O site, O(6) is bonded in a water-like geometry to one U(1) and one U(3) atom. In the second O site, O(7) is bonded in a distorted bent 150 degrees geometry to one U(1) and one U(2) atom. In the third O site, O(8) is bonded in a distorted single-bond geometry to one U(2) and one U(3) atom. In the fourth O site, O(1) is bonded in a distorted trigonal planar geometry to one U(3) and two equivalent U(1) atoms. In the fifth O site, O(9) is bonded in a single-bond geometry to one U(2) atom. In the sixth O site, O(2) is bonded in a 3-coordinate geometry to one U(3) and two equivalent U(1) atoms. In the seventh O site, O(10) is bonded in a distorted single-bond geometry to two equivalent U(2) atoms. In the eighth O site, O(3) is bonded in a bent 120 degrees geometry to one U(2) and one U(3) atom. In the ninth O site, O(4) is bonded in a single-bond geometry to one U(2) atom. In the tenth O site, O(5) is bonded in a bent 120 degrees geometry to one U(1) and one U(3) atom. is represented by the CIF card [CIF]
