MgOsGe2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgOsGe2 cluster. Mg(1) is bonded in a 2-coordinate geometry to one Os(1) and one Ge(2) atom. The Mg(1)-Os(1) bond length is 0.54 Å. The Mg(1)-Ge(2) bond length is 0.54 Å. Os(1) is bonded in a distorted single-bond geometry to one Mg(1), one Ge(1), and one Ge(2) atom. The Os(1)-Ge(1) bond length is 0.28 Å. The Os(1)-Ge(2) bond length is 0.23 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 2-coordinate geometry to one Os(1) and one Ge(2) atom. The Ge(1)-Ge(2) bond length is 0.28 Å. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to one Mg(1), one Os(1), and one Ge(1) atom.
