Materials Data on LiMnH6O7 by Materials Project
Li(H2O)3MnO4 crystallizes in the hexagonal P6_3mc space group. The structure is one-dimensional and consists of two mangan(iv)-hydroxyd molecules and one Li(H2O)3 ribbon oriented in the (0, 0, 1) direction. In the Li(H2O)3 ribbon, Li1+ is bonded to six equivalent O2- atoms to form face-sharing LiO6 octahedra. There are three shorter (2.16 Å) and three longer (2.17 Å) Li–O bond lengths. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. O2- is bonded in a distorted water-like geometry to two equivalent Li1+ and two equivalent H1+ atoms.
