The crystal structure described by Na2MgCu2TeO6 crystallizes in the triclinic P-1 space group. Na(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. Cu(1) is bonded in a linear geometry to one O(1) and one O(3) atom. Te(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1), one Cu(1), and one Te(1) atom to form a mixture of distorted corner and edge-sharing ONa2CuTe trigonal pyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to two equivalent Na(1), one Mg(1), and one Te(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Na(1), one Mg(1), one Cu(1), and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
