Ga Ni Os Os
Os2NiGa crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Os2NiGa cluster. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted single-bond geometry to one Ni(1) and one Ga(1) atom. The Os(1)-Ni(1) bond length is 1.75 Å. The Os(1)-Ga(1) bond length is 1.17 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Ni(1) atom. The Os(2)-Ni(1) bond length is 1.69 Å. Ni(1) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), and one Ga(1) atom. The Ni(1)-Ga(1) bond length is 1.52 Å. Ga(1) is bonded in a distorted single-bond geometry to one Os(1) and one Ni(1) atom.
