Materials Data on LiPH2 by Materials Project
LiPH2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Li1+ is bonded in a distorted body-centered cubic geometry to eight equivalent H1+ atoms. All Li–H bond lengths are 2.33 Å. P3- is bonded in a square co-planar geometry to four equivalent H1+ atoms. All P–H bond lengths are 1.81 Å. H1+ is bonded to four equivalent Li1+ and two equivalent P3- atoms to form a mixture of distorted face, edge, and corner-sharing HLi4P2 octahedra. The corner-sharing octahedra tilt angles range from 0–67°.
