The material structure described by K3MgMnO4 crystallizes in the monoclinic Cm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), and two equivalent O(1) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. Mg(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. Mn(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one K(2), two equivalent K(1), one Mg(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent K(1), two equivalent K(2), one Mg(1), and one Mn(1) atom. In the third O site, O(3) is bonded in a distorted trigonal bipyramidal geometry to one K(2), two equivalent K(1), one Mg(1), and one Mn(1) atom. is represented by the CIF file [CIF]
