The structure described by Li2(FeO2)3 crystallizes in the orthorhombic Cmce space group. Li(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing FeO6 octahedra. In the second Fe site, Fe(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing FeO6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Fe(1) and two equivalent Fe(2) atoms. In the second O site, O(2) is bonded to two equivalent Li(1), one Fe(1), and two equivalent Fe(2) atoms to form a mixture of distorted corner and edge-sharing OLi2Fe3 trigonal bipyramids. is represented by the CIF file [CIF]
