摘要：

The reaction of Na2IPdCl4 with diphenyl disulfide in methanol yields a polymeric compound of formula (Pd(SC6H5)Cl (I) containing alternating halogen and sulfur bridges. This compound is also formed by refluxing [Pd((C6H3)(2)S-2)Cl2S2 in methanol. The characterization of I was based on its infrared spectra and on its bridge-splitting reactions. In the reaction of I with a neutral ligand L (L = pyridine, triphenylphosphine, tripheiaylarsine)S-bridged complexes of the type (Pd(SCeH5)LCI)2 are formed. The reaction with ethylenediamine yields the cationic S-bridged complex (Pd(SC6H5(en)12C11, whereas with [As(C6H5)(4)Cl the cationic complex IPd(SC6H5)Cl-2](2)[As(C5H5)412 is formed. The above reactions involve only splitting of the bridges. When I reacts either with 1,2-bis(diphenylphosphino)ethane or with an excess of phosphine, both the halogen and sulfur bridges are cleaved. The nature of the products in the bridge-splitting reactions has been determined on the basis of elemental analysis, ir spectra, conductivity, and molecular weight ineasurements, where possible.
