Materials Data on TbH2 by Materials Project
TbH2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Tb is bonded in a body-centered cubic geometry to eight equivalent H atoms. All Tb–H bond lengths are 2.27 Å. H is bonded to four equivalent Tb atoms to form a mixture of edge and corner-sharing HTb4 tetrahedra.
