Sr Sr La Ru
Sr2LaRu crystallizes in the monoclinic Cm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Sr(2) and one Ru(1) atom. The Sr(1)-Sr(2) bond length is 2.55 Å. The Sr(1)-Ru(1) bond length is 0.97 Å. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to one Sr(1), four equivalent Sr(2), one La(1), and one Ru(1) atom. All Sr(2)-Sr(2) bond lengths are 3.69 Å. The Sr(2)-La(1) bond length is 3.36 Å. The Sr(2)-Ru(1) bond length is 2.94 Å. La(1) is bonded in a 6-coordinate geometry to one Sr(2), four equivalent La(1), and one Ru(1) atom. All La(1)-La(1) bond lengths are 3.69 Å. The La(1)-Ru(1) bond length is 4.25 Å. Ru(1) is bonded in a single-bond geometry to one Sr(1), one Sr(2), and one La(1) atom.
