The crystal structure described by Li2U3V2O15 crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded in a distorted T-shaped geometry to one O(3), two equivalent O(2), and two equivalent O(4) atoms. There are two inequivalent U sites. In the first U site, U(1) is bonded to one O(5), two equivalent O(2), and four equivalent O(1) atoms to form distorted UO7 pentagonal bipyramids that share  a cornercorner with one U(1)O7 pentagonal bipyramid, corners with two equivalent V(1)O4 tetrahedra, edges with two equivalent U(1)O7 pentagonal bipyramids, and  an edgeedge with one V(1)O4 tetrahedra. In the second U site, U(2) is bonded to two equivalent O(3) and four equivalent O(4) atoms to form UO6 octahedra that share corners with four equivalent V(1)O4 tetrahedra. V(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form VO4 tetrahedra that share corners with two equivalent U(2)O6 octahedra, corners with two equivalent U(1)O7 pentagonal bipyramids, and  an edgeedge with one U(1)O7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 38°. There are five inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one U(2), and one V(1) atom. In the second O site, O(5) is bonded in a linear geometry to two equivalent U(1) atoms. In the third O site, O(1) is bonded in a 3-coordinate geometry to two equivalent U(1) and one V(1) atom. In the fourth O site, O(2) is bonded in a linear geometry to one Li(1) and one U(1) atom. In the fifth O site, O(3) is bonded in a linear geometry to one Li(1) and one U(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
