The crystal structure described by Li5Pt2H9 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 5-coordinate geometry to one H(2) and four equivalent H(1) atoms. In the second Li site, Li(2) is bonded in a body-centered cubic geometry to eight equivalent H(1) atoms. Pt(1) is bonded to one H(2) and four equivalent H(1) atoms to form distorted corner-sharing PtH5 square pyramids. There are two inequivalent H sites. In the first H site, H(2) is bonded in an octahedral geometry to four equivalent Li(1) and two equivalent Pt(1) atoms. In the second H site, H(1) is bonded in a 4-coordinate geometry to one Li(2), two equivalent Li(1), and one Pt(1) atom. is represented by the CIF card [CIF]
