The structure described by BaTe2O6 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent O(3) and eight equivalent O(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with two equivalent Te(1)O6 octahedra and corners with four equivalent Te(2)O5 square pyramids. The corner-sharing octahedral tilt angles are 36°. In the second Te site, Te(2) is bonded to one O(3) and four equivalent O(1) atoms to form corner-sharing TeO5 square pyramids. The corner-sharing octahedral tilt angles are 59°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Te(1), and one Te(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Te(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one Te(2) atom. is represented by the CIF card [CIF]
