Re Tc Tc Ge
(Tc)2ReGe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReGe clusters and two Tc clusters. In each ReGe cluster, Re(1) is bonded in a single-bond geometry to one Ge(1) atom. The Re(1)-Ge(1) bond length is 1.23 Å. Ge(1) is bonded in a single-bond geometry to one Re(1) atom. In each Tc cluster, Tc(1) is bonded in a distorted single-bond geometry to one Tc(1) atom. The Tc(1)-Tc(1) bond length is 1.23 Å.
