The compound described by Li2CrMn2O6 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CrO6 octahedra that share edges with six equivalent Mn(1)O6 octahedra. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share edges with three equivalent Cr(1)O6 octahedra and edges with three equivalent Mn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Cr(1), and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing OLi2Mn2Cr trigonal bipyramids. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
