Synthesis, Solution Dynamics, and Crystal Structures of (2,2‘:6‘,2‘‘-Terpyridine)(η1- and η3-allyl)palladium(II) Complexes
摘要:
The palladium allyl complexes [(2,2':6',2 ''-terpyridine)Pd(C3H5)]x (1, X(-)=BF4-; 2, X(-)=ClO4-) were synthesized and characterized. The molecular structures of the eta(3)- and eta(1)-allyl isomeric forms of 2, where the terpyridine ligand coordinates the palladium atom either in a bidentate or in a tridentate fashion, were determined by X-ray crystallography, whereas a variable-temperature H-1 NMR analysis of 1 shows that the complex is fluxional.
