The material described by K11Mn4O16 crystallizes in the tetragonal I-42m space group. There are five inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. In the third K site, K(3) is bonded to four equivalent O(1) and four equivalent O(3) atoms to form distorted KO8 hexagonal bipyramids that share corners with four equivalent K(3)O8 hexagonal bipyramids, corners with four equivalent K(4)O6 pentagonal pyramids, and edges with four equivalent Mn(1)O4 tetrahedra. In the fourth K site, K(4) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form distorted KO6 pentagonal pyramids that share corners with four equivalent K(3)O8 hexagonal bipyramids, corners with two equivalent Mn(1)O4 tetrahedra, and edges with two equivalent Mn(1)O4 tetrahedra. In the fifth K site, K(5) is bonded in a 8-coordinate geometry to eight equivalent O(3) atoms. Mn(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form MnO4 tetrahedra that share  a cornercorner with one K(4)O6 pentagonal pyramid, edges with two equivalent K(3)O8 hexagonal bipyramids, and  an edgeedge with one K(4)O6 pentagonal pyramid. There are three inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one K(1), one K(2), one K(3), one K(4), one K(5), and one Mn(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(3), three equivalent K(1), and one Mn(1) atom. In the third O site, O(2) is bonded in a 6-coordinate geometry to one K(4), two equivalent K(1), two equivalent K(2), and one Mn(1) atom. is represented by the CIF card [CIF]
