The material structure described by Na2Mg(SbO3)2 crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(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 Na site, Na(2) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. Mg(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. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), one O(4), and one O(5) atom. In the second Sb site, Sb(2) 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 to one Na(1), one Na(2), one Mg(1), one Sb(1), and one Sb(2) atom to form a mixture of distorted corner and edge-sharing ONa2MgSb2 square pyramids. In the second O site, O(2) is bonded in a see-saw-like geometry to one Na(1), one Na(2), one Mg(1), and one Sb(2) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Mg(1), one Sb(1), and one Sb(2) atom. In the fourth O site, O(4) is bonded to one Na(1), one Na(2), one Mg(1), one Sb(1), and one Sb(2) atom to form a mixture of distorted corner and edge-sharing ONa2MgSb2 trigonal bipyramids. In the fifth O site, O(5) is bonded to one Na(1), one Na(2), one Mg(1), one Sb(1), and one Sb(2) atom to form a mixture of distorted corner and edge-sharing ONa2MgSb2 square pyramids. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to one Na(1), one Na(2), one Mg(1), and one Sb(2) atom. is represented by the CIF file [CIF]
