Li2MnO2 is Spinel-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 corner and edge-sharing LiO4 tetrahedra. Mn(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 Mn(1) atoms to form a mixture of distorted corner and edge-sharing OLi4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 0-46°.
Li2MnO2 is Spinel-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 corner and edge-sharing LiO4 tetrahedra. There are two shorter (1.98 Å) and two longer (2.00 Å) Li(1)-O(1) bond lengths. Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Mn(1)-O(1) bond lengths are 2.12 Å. O(1) is bonded to four equivalent Li(1) and two equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing OLi4Mn2 octahedra. The corner-sharing octahedral tilt angles range from 0-46°.
