The structure described by Pb2MgTeO6 crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form MgO6 octahedra that share corners with six equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 1-6°. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Te(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form TeO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 1-6°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Mg(1), one Pb(1), one Pb(2), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Mg(1), one Pb(1), one Pb(2), and one Te(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Mg(1), one Pb(1), one Pb(2), and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted linear geometry to one Mg(1), one Pb(1), one Pb(2), and one Te(1) atom. In the fifth O site, O(5) is bonded in a linear geometry to one Mg(1), one Pb(1), one Pb(2), and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted linear geometry to one Mg(1), one Pb(1), one Pb(2), and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
