Zn As Ru Ru
(Ru)2AsZn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ruthenium molecule and one AsZn cluster. In the AsZn cluster, Zn(1) is bonded in a single-bond geometry to one As(1) atom. The Zn(1)-As(1) bond length is 0.62 Å. As(1) is bonded in a single-bond geometry to one Zn(1) atom.
