Sr2RuCo crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2RuCo cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 1-coordinate geometry to one Co(1) atom. The Sr(1)-Co(1) bond length is 2.05 Å. In the second Sr site, Sr(2) is bonded in a 2-coordinate geometry to one Ru(1) and one Co(1) atom. The Sr(2)-Ru(1) bond length is 1.30 Å. The Sr(2)-Co(1) bond length is 1.29 Å. Ru(1) is bonded in a 2-coordinate geometry to one Sr(2) and one Co(1) atom. The Ru(1)-Co(1) bond length is 1.29 Å. Co(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Ru(1) atom.
