Sr2RuH6 crystallizes in the cubic Fm-3m space group. Sr(1) is bonded to twelve equivalent H(1) atoms to form SrH12 cuboctahedra that share corners with twelve equivalent Sr(1)H12 cuboctahedra, faces with six equivalent Sr(1)H12 cuboctahedra, and faces with four equivalent Ru(1)H6 octahedra. Ru(1) is bonded to six equivalent H(1) atoms to form RuH6 octahedra that share faces with eight equivalent Sr(1)H12 cuboctahedra. H(1) is bonded to four equivalent Sr(1) and one Ru(1) atom to form a mixture of face, corner, and edge-sharing HSr4Ru square pyramids.
