SrRu2Co crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a single-bond geometry to one Ru(2) and one Co(1) atom. The Sr(1)-Ru(2) bond length is 3.32 Å. The Sr(1)-Co(1) bond length is 1.45 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Ru(2) and one Co(1) atom. The Ru(1)-Ru(2) bond length is 2.94 Å. The Ru(1)-Co(1) bond length is 1.87 Å. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to one Sr(1), one Ru(1), and six equivalent Ru(2) atoms. All Ru(2)-Ru(2) bond lengths are 2.83 Å. Co(1) is bonded in a distorted linear geometry to one Sr(1) and one Ru(1) atom.
