Mg Mg Tc Os
Mg2TcOs is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mg2TcOs clusters. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a single-bond geometry to one Os(1) atom. The Mg(1)-Os(1) bond length is 0.73 Å. In the second Mg site, Mg(2) is bonded in a distorted linear geometry to one Tc(1) and one Os(1) atom. The Mg(2)-Tc(1) bond length is 1.49 Å. The Mg(2)-Os(1) bond length is 0.73 Å. Tc(1) is bonded in a single-bond geometry to one Mg(2) atom. Os(1) is bonded in a linear geometry to one Mg(1) and one Mg(2) atom.
