摘要: Abstract Palladium NOx-containing polynuclear carboxylate complexes Pd4(μ-CO)2(μ-NO)(μ-iPrCO2)5 and Pd8(μ-CO)4(μ-NO2)4(μ-iPrCO2)8 were studied with MALDI-TOF mass-spectroscopic technique. The results confirm previous suggestion about Pd4 metal chains as building blocks for big palladium carbonyl clusters. Also a new Pd3 bent chain observed in mass-spectra was demonstrated to serve block well. Using the data biggest cluster Pd12(μ-CO)8(μ-NO2)8(μ-iPrCO2)8 synthesized characterized by X-Ray analysis. Thus it shown that carboxylates can be used prediction of structures
