K Sb Sb Os
KOsSb2 is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KOsSb2 clusters. K(1) is bonded in a trigonal non-coplanar geometry to one Os(1) and two equivalent Sb(1) atoms. The K(1)-Os(1) bond length is 1.86 Å. Both K(1)-Sb(1) bond lengths are 1.74 Å. Os(1) is bonded in a single-bond geometry to one K(1) atom. Sb(1) is bonded in a single-bond geometry to one K(1) atom.
