Ga As As Os
OsGaAs2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsGaAs2 clusters. Os(1) is bonded in a distorted single-bond geometry to one Ga(1) atom. The Os(1)-Ga(1) bond length is 2.82 Å. Ga(1) is bonded in a single-bond geometry to one Os(1) and one As(2) atom. The Ga(1)-As(2) bond length is 1.17 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a single-bond geometry to one As(2) atom. The As(1)-As(2) bond length is 0.98 Å. In the second As site, As(2) is bonded in a linear geometry to one Ga(1) and one As(1) atom.
