The structure described by Li2FeO2 is Ilmenite-like structured and crystallizes in the orthorhombic Immm space group. Li(1) is bonded to four equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing LiO4 trigonal pyramids. Fe(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent Li(1) and two equivalent Fe(1) atoms to form a mixture of corner and edge-sharing OLi4Fe2 octahedra. The corner-sharing octahedral tilt angles range from 0-39°. is represented by the CIF file [CIF]
