Sr5Ga crystallizes in the monoclinic Cm space group. There are five inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a linear geometry to one Sr(2) and one Ga(1) atom. The Sr(1)-Sr(2) bond length is 0.84 Å. The Sr(1)-Ga(1) bond length is 1.62 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Sr(1) and one Sr(3) atom. The Sr(2)-Sr(3) bond length is 3.88 Å. In the third Sr site, Sr(3) is bonded to one Sr(2), one Sr(5), and four equivalent Sr(3) atoms to form a mixture of edge and corner-sharing SrSr6 octahedra. The corner-sharing octahedra are not tilted. The Sr(3)-Sr(5) bond length is 4.08 Å. All Sr(3)-Sr(3) bond lengths are 4.05 Å. In the fourth Sr site, Sr(4) is bonded in a single-bond geometry to one Sr(5) and one Ga(1) atom. The Sr(4)-Sr(5) bond length is 4.08 Å. The Sr(4)-Ga(1) bond length is 2.27 Å. In the fifth Sr site, Sr(5) is bonded to one Sr(3), one Sr(4), and four equivalent Sr(5) atoms to form a mixture of edge and corner-sharing SrSr6 octahedra. The corner-sharing octahedra are not tilted. All Sr(5)-Sr(5) bond lengths are 4.05 Å. Ga(1) is bonded in a linear geometry to one Sr(1) and one Sr(4) atom.
