Ba Tl Ru Ru
BaRu2Tl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BaRu2Tl cluster. Ba(1) is bonded in a bent 150 degrees geometry to one Ru(2) and one Tl(1) atom. The Ba(1)-Ru(2) bond length is 0.69 Å. The Ba(1)-Tl(1) bond length is 0.70 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a single-bond geometry to one Tl(1) atom. The Ru(1)-Tl(1) bond length is 1.35 Å. In the second Ru site, Ru(2) is bonded in a single-bond geometry to one Ba(1) atom. Tl(1) is bonded in a linear geometry to one Ba(1) and one Ru(1) atom.
