La2TeO6 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and two equivalent O(6) atoms. In the second La site, La(2) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms. 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(6) is bonded in a distorted trigonal non-coplanar geometry to two equivalent La(1) and one Te(1) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one Te(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to one La(1), two equivalent La(2), and one Te(1) atom. In the fourth O site, O(3) is bonded in a distorted trigonal planar geometry to one La(1), one La(2), and one Te(1) atom. In the fifth O site, O(4) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one Te(1) atom. In the sixth O site, O(5) is bonded to one La(1), two equivalent La(2), and one Te(1) atom to form distorted corner-sharing OLa3Te tetrahedra.
