The material structure described by K2Na2MgTi2O6 crystallizes in the monoclinic C2 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 2-coordinate geometry to two equivalent O(3) and two equivalent O(4) atoms. In the second K site, K(2) is bonded in a distorted see-saw-like geometry to two equivalent O(3) and two equivalent O(4) atoms. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted single-bond geometry to one O(3) and two equivalent O(1) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Mg(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a distorted trigonal bipyramidal geometry to one O(4), two equivalent O(1), and two equivalent O(2) atoms. In the second Ti site, Ti(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Mg(1), one Ti(1), and one Ti(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Na(2), one Mg(1), one Ti(1), and one Ti(2) atom. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), one Na(1), and one Ti(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent K(2), and one Ti(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
