The crystal structure described by TeSeO4 crystallizes in the monoclinic Cc space group. Te(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form distorted corner-sharing TeO5 square pyramids. Se(1) is bonded in a trigonal non-coplanar geometry to one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Te(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Te(1) and one Se(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Te(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Te(1) and one Se(1) atom. is represented by the CIF card [CIF]
