Materials Data on TmH2 by Materials Project
TmH2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tm is bonded in a body-centered cubic geometry to eight equivalent H atoms. All Tm–H bond lengths are 2.20 Å. H is bonded to four equivalent Tm atoms to form a mixture of edge and corner-sharing HTm4 tetrahedra.
