ReTcReAg crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReAg clusters and two ReTc clusters. In each ReAg cluster, Re(2) is bonded in a distorted single-bond geometry to one Ag(1) atom. The Re(2)-Ag(1) bond length is 1.77 Å. Ag(1) is bonded in a 1-coordinate geometry to one Re(2) atom. In each ReTc cluster, Re(1) is bonded in a single-bond geometry to one Tc(1) atom. The Re(1)-Tc(1) bond length is 1.20 Å. Tc(1) is bonded in a 1-coordinate geometry to one Re(1) atom.
