KUVO6 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), two equivalent O(4), and two equivalent O(6) atoms. U(1) is bonded to one O(3), one O(4), one O(6), and two equivalent O(1) atoms to form distorted UO5 square pyramids that share corners with two equivalent U(1)O5 square pyramids and  a cornercorner with one V(1)O4 tetrahedra. V(1) is bonded to one O(2), one O(3), and two equivalent O(5) atoms to form distorted VO4 tetrahedra that share  a cornercorner with one U(1)O5 square pyramid and  an edgeedge with one V(1)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent U(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1) and one V(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one U(1), and one V(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one U(1) atom. In the fifth O site, O(5) is bonded in an L-shaped geometry to two equivalent V(1) atoms. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to two equivalent K(1) and one U(1) atom.
