Al Ni Os
OsNiAl is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsNiAl clusters. Os(1) is bonded in a linear geometry to one Ni(1) and one Al(1) atom. The Os(1)-Ni(1) bond length is 0.02 Å. The Os(1)-Al(1) bond length is 0.13 Å. Ni(1) is bonded in a single-bond geometry to one Os(1) atom. Al(1) is bonded in a single-bond geometry to one Os(1) atom.
