ReTc2Ag is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReTc2Ag clusters. Re(1) is bonded in a single-bond geometry to two equivalent Tc(1) and one Ag(1) atom. Both Re(1)-Tc(1) bond lengths are 0.26 Å. The Re(1)-Ag(1) bond length is 0.14 Å. Tc(1) is bonded in a 3-coordinate geometry to one Re(1), one Tc(1), and one Ag(1) atom. The Tc(1)-Tc(1) bond length is 0.14 Å. The Tc(1)-Ag(1) bond length is 0.26 Å. Ag(1) is bonded in a distorted single-bond geometry to one Re(1) and two equivalent Tc(1) atoms.
