K2MgTi2O5 crystallizes in the monoclinic C2 space group. K(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. Mg(1) is bonded in a linear geometry to two equivalent O(2) atoms. Ti(1) is bonded to one O(2), one O(3), and three equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing TiO5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(1) and three equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent K(1), one Mg(1), and one Ti(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to four equivalent K(1) and two equivalent Ti(1) atoms.
