UV2O8 crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms. V(1) is bonded to one O(1), one O(3), one O(5), and two equivalent O(2) atoms to form distorted corner-sharing VO5 trigonal bipyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one U(1) and one V(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent U(1) atoms. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one U(1) and one V(1) atom.
UV2O8 crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms. Both U(1)-O(1) bond lengths are 2.63 Å. There is one shorter (2.03 Å) and one longer (2.18 Å) U(1)-O(4) bond length. Both U(1)-O(5) bond lengths are 1.87 Å. V(1) is bonded to one O(1), one O(3), one O(5), and two equivalent O(2) atoms to form distorted corner-sharing VO5 trigonal bipyramids. The V(1)-O(1) bond length is 1.66 Å. The V(1)-O(3) bond length is 1.83 Å. The V(1)-O(5) bond length is 2.21 Å. There is one shorter (1.80 Å) and one longer (1.81 Å) V(1)-O(2) bond length. There are five inequivalent O sites.
