(Ru)4(RuAl2)3 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of two Ru clusters and two RuAl2 clusters. In each Ru cluster, there are two inequivalent Ru sites. In the first Ru site, Ru(3) is bonded in a distorted single-bond geometry to one Ru(1,4,5) atom. The Ru(3)-Ru(1,4,5) bond length is 1.31 Å. In the second Ru site, Ru(1,4,5) is bonded in a 1-coordinate geometry to one Ru(3) atom. In one of the RuAl2 clusters, there are two inequivalent Ru sites. In the first Ru site, Ru(6) is bonded in a distorted single-bond geometry to one Al(6) atom. The Ru(6)-Al(6) bond length is 1.66 Å. In the second Ru site, Ru(7) is bonded in a single-bond geometry to one Al(1) and one Al(4) atom. The Ru(7)-Al(1) bond length is 1.92 Å. The Ru(7)-Al(4) bond length is 0.44 Å. There are four inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted linear geometry to one Ru(7) and one Al(6) atom. The Al(1)-Al(6) bond length is 0.25 Å. In the second Al site, Al(3) is bonded in a single-bond geometry to one Al(4) atom. The Al(3)-Al(4) bond length is 0.31 Å. In the third Al site, Al(4) is bonded in a distorted linear geometry to one Ru(7) and one Al(3) atom. In the fourth Al site, Al(6) is bonded in a distorted bent 120 degrees geometry to one Ru(6) and one Al(1) atom. In one of the RuAl2 clusters, Ru(2) is bonded in a distorted single-bond geometry to one Al(5) atom. The Ru(2)-Al(5) bond length is 1.66 Å. There are two inequivalent Al sites. In the first Al site, Al(2) is bonded in a single-bond geometry to one Al(5) atom. The Al(2)-Al(5) bond length is 0.25 Å. In the second Al site, Al(5) is bonded in a distorted bent 120 degrees geometry to one Ru(2) and one Al(2) atom.
