LiCoMnO4 crystallizes in the orthorhombic Imma space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Co(1)O6 octahedra, edges with two equivalent Li(1)O6 octahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-11°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share edges with two equivalent Mn(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Li(1)O6 octahedra, edges with two equivalent Li(1)O6 octahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 10-11°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Mn(1), and two equivalent Co(1) atoms to form a mixture of corner and edge-sharing OLi2MnCo2 square pyramids. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Mn(1), and one Co(1) atom.
