Abstract Four new mixed-ligand complexes of pailadiumt(Ⅱ) with L1(N-benzoyl-α-amino acid dianion) and L2[ethyldiamine (en),2,2’-bipyridine (Bpy) and 1,10-phenanthroline (Phen)] were synthesized.Ail the complexes have been characterized by elemental analyses,molar conductance,infrared and 1H NMR spectra and therme-gravimetric analyses.Crystal structures of [Pd(Bpy)(Bzval-N,O)] and [Pd(en) (Bzphe-N,O)] H2O have been do termmed by X-ray diffraction analysis.The results indicate that in all the complexes hgand L1 coordinates to palladium (Ⅱ) through deprotonated amide nitrogen and carboxylic oxygen,and there are some intramolecular nonrovalent in teractions in the complexes.
AbstractList Four new mixed-ligand complexes of palladium (II) with L1 (N-benwyl-α-amino acid dianion) and L2 [ethyldiamine (en), 2. 2′-bipyridine (Bpy) and 1.10-phenanthroline (Phen)] were synthesized. All the complexes have been characterized by elemental analyses, molar conductance, infrared and1H NMR spectra and thermo-gravimetric analyses. Crystal structures of [Pd(Bpy)(Bzval-N, O)] and [Pd(en)(Bzphe-N, O) ·H2O have been determined by X-ray diffraction analysis. The results indicate that in all the complexes’ ligand L1 coordinates to palladium (II) through deprotonated amide nitrogen and carboxylic oxygen, and there are some intramolecular noncovalent interactions in the complexes.
