B2TeO6 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(6) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(1), one O(4), and one O(5) atom. Te(1) is bonded in an octahedral geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one B(2) and one Te(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one B(1) and one Te(1) atom. In the third O site, O(3) is bonded in an L-shaped geometry to one B(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one B(2) and one Te(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one B(2) and one Te(1) atom. In the sixth O site, O(6) is bonded in an L-shaped geometry to one B(1) and one Te(1) atom.
