The crystal structure described by Li2U3P2O15 crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(1), and four equivalent O(4) atoms. In the second U site, U(2) is bonded to two equivalent O(5) and four equivalent O(3) atoms to form UO6 octahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with two equivalent U(2)O6 octahedra. The corner-sharing octahedral tilt angles are 36°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one U(2) atom. In the second O site, O(1) is bonded in a bent 150 degrees geometry to one Li(1) and one U(1) atom. In the third O site, O(2) is bonded in a linear geometry to two equivalent U(1) atoms. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one Li(1), one U(2), and one P(1) atom. In the fifth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent U(1) and one P(1) atom. is represented by the CIF card [CIF]
