Mn2CrO4 is Spinel-like structured and crystallizes in the monoclinic C2/c space group. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 octahedra that share corners with six equivalent Mn(2)O4 tetrahedra, edges with two equivalent Cr(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent Mn(2)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Cr(1)O6 octahedra. In the second Mn site, Mn(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with six equivalent Cr(1)O6 octahedra and corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-63°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Cr(1), one Mn(2), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to two equivalent Cr(1), one Mn(1), and one Mn(2) atom.
