Ga Si Os Os
Os2GaSi crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 4-coordinate geometry to one Os(2), two equivalent Ga(1), and one Si(1) atom. The Os(1)-Os(2) bond length is 2.24 Å. There is one shorter (2.42 Å) and one longer (3.15 Å) Os(1)-Ga(1) bond length. The Os(1)-Si(1) bond length is 2.51 Å. In the second Os site, Os(2) is bonded in a 1-coordinate geometry to one Os(1) and one Si(1) atom. The Os(2)-Si(1) bond length is 1.28 Å. Ga(1) is bonded in a single-bond geometry to two equivalent Os(1) and one Si(1) atom. The Ga(1)-Si(1) bond length is 0.76 Å. Si(1) is bonded in a 2-coordinate geometry to one Os(1), one Os(2), and one Ga(1) atom.
