LiMnO2 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to four equivalent O(1) atoms to form distorted LiO4 trigonal pyramids that share corners with eight equivalent Mn(1)O6 octahedra, corners with four equivalent Li(1)O4 trigonal pyramids, and edges with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 23-73°. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with eight equivalent Li(1)O4 trigonal pyramids, edges with six equivalent Mn(1)O6 octahedra, and edges with two equivalent Li(1)O4 trigonal pyramids. O(1) is bonded to two equivalent Li(1) and three equivalent Mn(1) atoms to form a mixture of distorted corner and edge-sharing OLi2Mn3 trigonal bipyramids.
