title: Monomers and polymers of tripalladium(0) ditropylium halides.
abstract: The synthesis and characterization of a series of polymeric complexes based upon a central tripalladium ditropylium (Tr) unit [Pd(3)Tr(2)] and containing different halide ligands are reported. The complexes were synthesized in good yield and characterized by multinuclei NMR spectroscopy, mass spectrometry, microanalysis, and X-ray crystallography. An unexpected product was an inorganic polymer consisting of linked individual tripalladium ditropylium units [Pd(3)Tr(2)X(2)](infinity) (X = Cl, Br, and I); this is the first reported, crystallographically characterized example of polymeric tripalladium complexes with halide ligands.
