La Ni Os Os
LaNi(Os)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two lanthanum;nickel molecules and two Os clusters. In each Os cluster, there are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Os(2) atom. The Os(1)-Os(2) bond length is 0.98 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Os(1) atom.
