KU(TeO4)2 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. U(1) is bonded in an octahedral geometry to two equivalent O(1) and four equivalent O(2) atoms. Te(1) is bonded in a rectangular see-saw-like geometry to one O(3), one O(4), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1) and one U(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one U(1), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to two equivalent K(1) and two equivalent Te(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Te(1) atoms.
