Re Re Tc Os
Re2TcOs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Re2TcOs clusters. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a single-bond geometry to one Os(1) atom. The Re(1)-Os(1) bond length is 1.89 Å. In the second Re site, Re(2) is bonded in a single-bond geometry to one Tc(1) atom. The Re(2)-Tc(1) bond length is 1.71 Å. Tc(1) is bonded in a distorted linear geometry to one Re(2) and one Os(1) atom. The Tc(1)-Os(1) bond length is 2.59 Å. Os(1) is bonded in a 2-coordinate geometry to one Re(1) and one Tc(1) atom.
