Flash Communication: Pd₂Zn₂ Clusters from the Reduction of Palladium(II) Dichloride Precursors with Metallic Zinc.

ABSTRACT: We report the synthesis and solid-state characterization of two unusual Pd₂Zn₂ clusters formed from the partial reduction of [PdL₂Cl₂] precursors (L₂ = dcpe or dppe) with metallic zinc. The new clusters have been characterized by single crystal X-ray diffraction and contain a Pd₂Zn₂Cl₃ core capped by two chelating phosphine ligands with Zn in the formal +1.5 oxidation state. While they possess a near tetrahedral arrangement of metal ions, calculations and bonding analysis (NBO, AIM) suggest that there is limited Zn- - -Zn bonding in these species. Characterization in the solution state is suggestive of dynamic behavior on dissolution, with both diamagnetic and paramagnetic species observed by NMR and EP
