  摘要：

  The H-1 NMR, electronic absorption, and luminescence spectra, as well as voltammograms of the reduction and oxidation of the complexes [Pd(Ca N)(Na N)]ClO4 and [Pd(Ca N)(mu-OOCCH3)](2) [where (Ca N)(-) is deprotonated 2-phenyl-4,5-dihydro-1,3-oxazole, and Na N is ethylenediamine or 2,2'-bipyridine (bpy)] were compared. Magnetic nonequivalence of protons in the dihydrooxazole ring and upfield shift of the corresponding signals were observed as a result of anisotropic effect of the ring current in palladated phenyl substituents in the [Pd(Ca N)(mu-OOCCH3)](2) complex having a C (2) symmetry. One-electron reduction wave of [Pd(Ca N)bpy](+) was assigned to ligand-centered electron transfer to the pi* orbital of 2,2'-bipyridine, and two oxidation waves of [Pd(Ca N)(mu-OOCCH3)](2) were attributed to successive one-electron oxidations of the palladium centers. Low-temperature (77 K) phosphorescence of [Pd(Ca N)En](+) and [Pd(Ca N)bpy](+) was ascribed to optical transition localized on the metal-complex fragment {Pd(Ca N)} and to interligand charge transfer between the chelating and cyclopalladated ligands. The formation of metal-metal bond in the complex [Pd(Ca N)(mu-OOCCH3())](2) gives rise to radiative decay of photoexcitation energy from two electronically excited states, one of which is localized on the {Pd(Ca N)} fragment, and the second corresponds to the charge transfer metal-metal-cyclopalladated ligand.
