MgOs2Cl is Indium structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgOs2Cl cluster. Mg(1) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), and one Cl(1) atom. The Mg(1)-Os(1) bond length is 1.84 Å. The Mg(1)-Os(2) bond length is 1.02 Å. The Mg(1)-Cl(1) bond length is 1.84 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted single-bond geometry to one Mg(1) atom. In the second Os site, Os(2) is bonded in a single-bond geometry to one Mg(1) atom. Cl(1) is bonded in a distorted single-bond geometry to one Mg(1) atom.
