Re Tc Tc Ru
(Tc)2RuRe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuRe clusters and two Tc clusters. In each RuRe cluster, Re(1) is bonded in a single-bond geometry to one Ru(1) atom. The Re(1)-Ru(1) bond length is 1.14 Å. Ru(1) is bonded in a single-bond geometry to one Re(1) atom. In each Tc cluster, Tc(1) is bonded in a 1-coordinate geometry to one Tc(1) atom. The Tc(1)-Tc(1) bond length is 1.14 Å.
