Abstract

The decanuclear palladium cluster compounds [Pdio(u-CO)g(^3-CO)4 (PEtglg] and [Pdio(/(-CO)g(ii3-CO)2(//-CNXyl)2(PEt3)g] (Xyl = CgH^M^- 2,6) have been synthesised and characterised by a combination of spectroscopic data and single crystal X-ray crystallographic analyses. The former has a distorted tetracapped octahedral skeletal geometry and the latter a hexacapped tetrahedral geometry. The latter is unique in cluster chemistry and the structural change induced by the addition of isocyanide represents an interesting example of the effect of the steric requirements of the isocyanide ligand influencing the total electron count and geometry of the cluster. [Pdio(/<-CO)8(/i3-CO)4(PEt3)g] reacts with SO2 to give [Pd5(/(-S02)2(p3-S02)2(PEt3)5].
