Y Mg Mg Os
Mg2YOs crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Mg2YOs cluster. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Mg(1)-Os(1) bond length is 1.23 Å. In the second Mg site, Mg(2) is bonded in a distorted single-bond geometry to one Y(1) atom. The Mg(2)-Y(1) bond length is 1.51 Å. Y(1) is bonded in a single-bond geometry to one Mg(2) and one Os(1) atom. The Y(1)-Os(1) bond length is 0.45 Å. Os(1) is bonded in a distorted single-bond geometry to one Mg(1) and one Y(1) atom.
