Ag Ag Ru Ru
RuAg crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one RuAg cluster. Ru(1) is bonded in a single-bond geometry to one Ag(1) atom. The Ru(1)-Ag(1) bond length is 0.41 Å. Ag(1) is bonded in a water-like geometry to one Ru(1) and one Ag(1) atom. The Ag(1)-Ag(1) bond length is 0.51 Å.
