Na2MgTiO3 crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), and two equivalent O(3) atoms. In the second Na site, Na(2) is bonded in a distorted pentagonal planar geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. Mg(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), and two equivalent O(2) atoms. Ti(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Na(1), two equivalent Na(2), one Mg(1), and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded to one Na(1), one Na(2), two equivalent Mg(1), and two equivalent Ti(1) atoms to form ONa2Mg2Ti2 octahedra that share edges with two equivalent O(2)Na2Mg2Ti2 octahedra and edges with four equivalent O(3)Na4MgTi octahedra. In the third O site, O(3) is bonded to two equivalent Na(1), two equivalent Na(2), one Mg(1), and one Ti(1) atom to form ONa4MgTi octahedra that share edges with two equivalent O(3)Na4MgTi octahedra and edges with four equivalent O(2)Na2Mg2Ti2 octahedra.
