The material structure described by YMn2O4 is Spinel-like structured and crystallizes in the monoclinic Cc space group. Y(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form YO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Y(1)O6 octahedra, and edges with four equivalent Mn(2)O6 octahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form MnO4 tetrahedra that share corners with six equivalent Y(1)O6 octahedra and corners with six equivalent Mn(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-65°. In the second Mn site, Mn(2) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with four equivalent Y(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Y(1), one Mn(1), and two equivalent Mn(2) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Y(1), one Mn(1), and two equivalent Mn(2) atoms. In the third O site, O(3) is bonded to two equivalent Y(1), one Mn(1), and one Mn(2) atom to form a mixture of distorted corner and edge-sharing OY2Mn2 trigonal pyramids. In the fourth O site, O(4) is bonded to two equivalent Y(1), one Mn(1), and one Mn(2) atom to form a mixture of distorted corner and edge-sharing OY2Mn2 trigonal pyramids. is represented by the CIF file [CIF]
