The material described by K4TiO4 crystallizes in the monoclinic P2_1/c space group. There are four inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to one O(3), two equivalent O(2), and three equivalent O(1) atoms. In the second K site, K(2) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form distorted KO5 square pyramids that share corners with three equivalent Ti(1)O4 tetrahedra,  an edgeedge with one K(2)O5 square pyramid, and  an edgeedge with one Ti(1)O4 tetrahedra. In the third K site, K(3) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(4) atoms. In the fourth K site, K(4) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(3), and two equivalent O(4) atoms. Ti(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form TiO4 tetrahedra that share corners with three equivalent K(2)O5 square pyramids and  an edgeedge with one K(2)O5 square pyramid. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent K(2), three equivalent K(1), and one Ti(1) atom.
