The crystal structure described by K2NaMgTiOF5 crystallizes in the monoclinic Cm space group. K(1) is bonded in a 6-coordinate geometry to one O(1), one F(1), one F(3), and three equivalent F(2) atoms. Na(1) is bonded in a rectangular see-saw-like geometry to one O(1), one F(1), one F(3), and one F(4) atom. Mg(1) is bonded in a rectangular see-saw-like geometry to one O(1), one F(1), one F(3), and one F(4) atom. Ti(1) is bonded in an octahedral geometry to one O(1), one F(1), one F(3), one F(4), and two equivalent F(2) atoms. O(1) is bonded to two equivalent K(1), one Na(1), one Mg(1), and one Ti(1) atom to form distorted OK2NaMgTi trigonal bipyramids that share  an edgeedge with one F(1)K2NaMgTi trigonal bipyramid and  a faceface with one F(1)K2NaMgTi trigonal bipyramid. There are four inequivalent F sites. In the first F site, F(1) is bonded to two equivalent K(1), one Na(1), one Mg(1), and one Ti(1) atom to form distorted FK2NaMgTi trigonal bipyramids that share  an edgeedge with one O(1)K2NaMgTi trigonal bipyramid and  a faceface with one O(1)K2NaMgTi trigonal bipyramid. In the second F site, F(2) is bonded in a 4-coordinate geometry to three equivalent K(1) and one Ti(1) atom. In the third F site, F(3) is bonded in a distorted T-shaped geometry to two equivalent K(1), one Na(1), one Mg(1), and one Ti(1) atom. In the fourth F site, F(4) is bonded in a T-shaped geometry to one Na(1), one Mg(1), and one Ti(1) atom. is represented by the CIF file [CIF]
