Ba2OsH6 crystallizes in the cubic Fm-3m space group. Ba(1) is bonded to twelve equivalent H(1) atoms to form BaH12 cuboctahedra that share corners with twelve equivalent Ba(1)H12 cuboctahedra, faces with six equivalent Ba(1)H12 cuboctahedra, and faces with four equivalent Os(1)H6 octahedra. Os(1) is bonded to six equivalent H(1) atoms to form OsH6 octahedra that share faces with eight equivalent Ba(1)H12 cuboctahedra. H(1) is bonded to four equivalent Ba(1) and one Os(1) atom to form a mixture of corner, edge, and face-sharing HBa4Os square pyramids.
