Re Ni Os
ReOsNi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReOsNi clusters. Re(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Re(1)-Os(1) bond length is 1.56 Å. Os(1) is bonded in a linear geometry to one Re(1) and one Ni(1) atom. The Os(1)-Ni(1) bond length is 1.06 Å. Ni(1) is bonded in a single-bond geometry to one Os(1) atom.
