The structure described by TeSeO4 crystallizes in the orthorhombic Ima2 space group. Te(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted corner-sharing TeO5 square pyramids. Se(1) is bonded in a trigonal non-coplanar geometry to one O(3) and two equivalent O(2) atoms. There are three 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. is represented by the Crystallographic Information File (CIF) [CIF]
