Nanosized [Pd₆₉(CO)₃₆(PEt₃)₁₈]: Metal‐Core Geometry Containing a Linear Assembly of Three Face‐Sharing Centered Pd₃₃ Icosahedra Inside of a Hexagonal‐Shaped Pd₃₀ Tube

Abstract

The nanosized icosahedral-based cluster [Pd69(CO)36(PEt3)18] (see picture) exhibits two new salient stereochemical features: 1) a linear face-condensation of three centered icosahedra that gives rise to a linear face-sharing Pd33-centered triicosahedron, and 2) a hexagonal-shaped Pd30 tube formed by cyclic trans edge-sharing of six Pd7-centered hexagons (host), inside of which resides the linear triicosahedron (permanent guest).
