Materials Data on Ca2H6Os by Materials Project
Ca2OsH6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ca2+ is bonded to twelve equivalent H+0.33- atoms to form CaH12 cuboctahedra that share corners with twelve equivalent CaH12 cuboctahedra, faces with six equivalent CaH12 cuboctahedra, and faces with four equivalent OsH6 octahedra. All Ca–H bond lengths are 2.56 Å. Os2- is bonded to six equivalent H+0.33- atoms to form OsH6 octahedra that share faces with eight equivalent CaH12 cuboctahedra. All Os–H bond lengths are 1.73 Å. H+0.33- is bonded to four equivalent Ca2+ and one Os2- atom to form a mixture of face, edge, and corner-sharing HCa4Os square pyramids.
