The material structure described by K4TiO4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form KO4 tetrahedra that share corners with two equivalent K(1)O4 tetrahedra, corners with four equivalent K(2)O4 tetrahedra, corners with four equivalent Ti(1)O4 tetrahedra,  an edgeedge with one K(1)O4 tetrahedra, and edges with two equivalent K(2)O4 tetrahedra. In the second K site, K(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted KO4 tetrahedra that share corners with two equivalent K(2)O4 tetrahedra, corners with four equivalent K(1)O4 tetrahedra, corners with four equivalent Ti(1)O4 tetrahedra,  an edgeedge with one K(2)O4 tetrahedra, and edges with two equivalent K(1)O4 tetrahedra. Ti(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form TiO4 tetrahedra that share corners with eight equivalent K(1)O4 tetrahedra and corners with eight equivalent K(2)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Ti(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Ti(1) atom. is represented by the CIF file [CIF]
