The material described by U(PO3)4 crystallizes in the triclinic P-1 space group. U(1) is bonded in a 8-coordinate geometry to one O(11), one O(12), one O(2), one O(4), one O(5), one O(7), one O(8), and one O(9) atom. There are four inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(10), one O(11), and one O(4) atom to form corner-sharing PO4 tetrahedra.

In the third P site, P(3) is bonded to one O(12), one O(3), one O(6), and one O(9) atom to form corner-sharing PO4 tetrahedra. In the fourth P site, P(4) is bonded to one O(3), one O(5), one O(6), and one O(8) atom to form corner-sharing PO4 tetrahedra. There are twelve inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one U(1) and one P(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one P(3) and one P(4) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one U(1) and one P(1) atom.

In the eighth O site, O(8) is bonded in a distorted bent 150 degrees geometry to one U(1) and one P(4) atom. In the ninth O site, O(9) is bonded in a distorted bent 150 degrees geometry to one U(1) and one P(3) atom. In the tenth O site, O(10) is bonded in a linear geometry to one P(1) and one P(2) atom.
