Zn Zn Ru Ru
ZnRu is alpha carbon monoxide-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two ZnRu clusters. Ru(1) is bonded in a single-bond geometry to one Zn(1) atom. The Ru(1)-Zn(1) bond length is 0.47 Å. Zn(1) is bonded in a single-bond geometry to one Ru(1) atom.
