LiPH2 crystallizes in the tetragonal P4/mmm space group. Li(1) is bonded in a distorted body-centered cubic geometry to eight equivalent H(1) atoms. P(1) is bonded in a square co-planar geometry to four equivalent H(1) atoms. H(1) is bonded to four equivalent Li(1) and two equivalent P(1) atoms to form a mixture of distorted corner, edge, and face-sharing HLi4P2 octahedra. The corner-sharing octahedral tilt angles range from 0-67°.
