The structure described by BaSr4U3O14 crystallizes in the orthorhombic Cmce space group. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(4) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Sr site, Sr(2) is bonded to one O(3), two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted SrO7 pentagonal bipyramids that share  a cornercorner with one U(1)O6 octahedra, corners with two equivalent U(2)O6 octahedra,  an edgeedge with one U(1)O6 octahedra, and edges with two equivalent U(2)O6 octahedra.
