The material structure described by KMn3O6 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 6-coordinate geometry to one O(1), one O(3), one O(4), one O(6), and two equivalent O(5) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form distorted edge-sharing MnO6 octahedra. In the second Mn site, Mn(2) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(6) atoms to form edge-sharing MnO6 octahedra. In the third Mn site, Mn(3) is bonded to one O(2), one O(3), one O(4), one O(6), and two equivalent O(5) atoms to form edge-sharing MnO6 octahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(1), one Mn(2), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Mn(3) and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one Mn(1), one Mn(2), and one Mn(3) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one Mn(1), one Mn(2), and one Mn(3) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent K(1), one Mn(2), and two equivalent Mn(3) atoms. In the sixth O site, O(6) is bonded to one K(1), one Mn(3), and two equivalent Mn(2) atoms to form distorted edge-sharing OKMn3 trigonal pyramids. is represented by the CIF card [CIF]
