K4MgTi2O6 crystallizes in the monoclinic C2 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 3-coordinate geometry to one O(1), one O(3), one O(4), and one O(5) atom. In the second K site, K(2) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(3), and one O(5) atom. Mg(1) is bonded in a bent 120 degrees geometry to two equivalent O(1) atoms. Ti(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted edge-sharing TiO5 trigonal bipyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Mg(1), and one Ti(1) atom. In the second O site, O(2) is bonded in a distorted tetrahedral geometry to two equivalent K(2) and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent K(1), two equivalent K(2), and two equivalent Ti(1) atoms.
