KDyTi4O12 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(5) atoms. Dy(1) is bonded in a 10-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. Ti(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 4-28°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one K(1), one Dy(1), and two equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a distorted square co-planar geometry to one K(1), one Dy(1), and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Dy(1) and two equivalent Ti(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Dy(1) and two equivalent Ti(1) atoms. In the fifth O site, O(5) is bonded in a distorted square co-planar geometry to two equivalent K(1) and two equivalent Ti(1) atoms.
