  Conformational preference of the side chain aromatic ring in Cu(II) and Pd(II) complexes of 2N1O-donor ligands

  摘要：

  Synthetic, structural, and spectroscopic studies were performed on the copper(H) and palladium(II) complexes of various 2N1O-donor tripod-like ligands containing a pyridine or a dimethylamine nitrogen, a tertiary amine nitrogen, and a phenolate oxygen as donor atoms and a pendent indole ring. [Pd(impp)Cl].3H(2)O.CH3CN (impp = N-2-pyridylmethyl-N-2-hydroxybenzyl-3-aminomethylindole) and two other Pd(II) complexes and a Cu(II) complex were isolated as crystals and structurally characterized by the X-ray diffraction method. The indole moiety of the Pd(II) complexes was found to be located close to the pyridine ring or the dimethylamino group and away from the phenolate moiety. H-1 NMR spectra of the Pd(II) complexes in CD3CN exhibited large upfield shifts of the pyridine and dimethylamino proton signals due to the pendent indole ring, supporting that the complexes in solution have a stacked structure similar to that found in the solid state. These findings indicated that the aromatic ring stacking interactions or CH-pi interactions exist between the indole and the pyridine rings or the methyl groups, respectively. [Cu-2(impp)(2)](ClO4)(2).H2O was revealed to have a dimeric structure with the indole moiety close to both the Cu(II) center and the pyridine ring, which suggests the possibility that the Cu(II) ion may undergo metal-aromatic ring interactions.
