TcRu(Cu)2 is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two copper, mol. (cu2) molecules and two TcRu clusters. In each TcRu cluster, Tc(1) is bonded in a single-bond geometry to one Ru(1) atom. The Tc(1)-Ru(1) bond length is 0.10 Å. Ru(1) is bonded in a single-bond geometry to one Tc(1) atom.
