ReTcOs2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ReTcOs2 cluster. Re(1) is bonded in a 3-coordinate geometry to one Tc(1), one Os(1), and one Os(2) atom. The Re(1)-Tc(1) bond length is 0.23 Å. The Re(1)-Os(1) bond length is 0.34 Å. The Re(1)-Os(2) bond length is 0.51 Å. Tc(1) is bonded in a 2-coordinate geometry to one Re(1), one Os(1), and one Os(2) atom. The Tc(1)-Os(1) bond length is 0.23 Å. The Tc(1)-Os(2) bond length is 0.53 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Re(1), one Tc(1), and one Os(2) atom. The Os(1)-Os(2) bond length is 0.51 Å. In the second Os site, Os(2) is bonded in a 3-coordinate geometry to one Re(1), one Tc(1), and one Os(1) atom.
