The material structure described by KMgCr2Mn2O10 crystallizes in the monoclinic Cm space group. K(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms. Mg(1) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(8), and two equivalent O(6) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one O(1), one O(3), and two equivalent O(5) atoms to form CrO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-54°. In the second Cr site, Cr(2) is bonded to one O(2), one O(4), and two equivalent O(6) atoms to form CrO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-59°. Mn(1) is bonded to one O(1), one O(2), one O(5), one O(6), one O(7), and one O(8) atom to form MnO6 octahedra that share corners with two equivalent Cr(1)O4 tetrahedra, corners with two equivalent Cr(2)O4 tetrahedra, and edges with two equivalent Mn(1)O6 octahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Cr(1), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Cr(2) and two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1), one Mg(1), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one K(1) and one Cr(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one K(1), one Cr(1), and one Mn(1) atom. In the sixth O site, O(6) is bonded to one K(1), one Mg(1), one Cr(2), and one Mn(1) atom to form a mixture of distorted corner and edge-sharing OKMgMnCr trigonal pyramids. In the seventh O site, O(7) is bonded in a water-like geometry to two equivalent Mn(1) atoms. In the eighth O site, O(8) is bonded in a trigonal non-coplanar geometry to one Mg(1) and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
