Reactions of bis(trifluoroacetylacetonato)palladium(II), , with tertiary phosphines followed by pyridine or its derivatives afforded a series of the -type complexes which contain a C,O-chelating trifluoroacetylacetonate dianion and a couple of tertiary phosphine and/or heterocyclic nitrogen base ligands (L and L').Their structures in solution were studied by 1H, 13C, 19F, and 31P NMR spectroscopy and the molecular structure in a crystal of *C6H6 containing triphenylphosphine and 2,6-dimethylpyridine as L and L' was determined by means of X-ray diffraction.
