TL;DR: In this article, the formation of two complexes by reaction of [PdCl4]2- with 1,2,3-triphenylguanidine (PhNH)2C=NPh under different metal/ligand ratios has been observed and the structure of the complex has been determined by X-ray diffraction methods.
Abstract: The formation of two complexes by reaction of [PdCl4]2- with 1,2,3-triphenylguanidine (PhNH)2C=NPh under different metal/ligand ratios has been observed and the structure of the complex [(1,2,3-triphenylguanidine)2PdCl2] has been determined by X-ray diffraction methods. The ligands are coordinated as neutral monodentate molecules to the metal centre through their imine nitrogen atoms. The second Pd(II) complex is [Pd(1,2,3-triphenylguanidine)4]2+ and was isolated by precipitation with ClO− 4.

TL;DR: In this paper, the formation of three new Pd(III) complex species was proved by means of EPR and magnetochemical methods resulting from the reaction of PdCl42− and 8-aminoquinoline (8-AQ) in basic (aqueous or aqueous-methanolic) medium.
Abstract: By means of EPR and magnetochemical methods the formation of 3 new Pd(III) complex species is proved resulting from the reaction of PdCl42− and 8-aminoquinoline (8-AQ) in basic (aqueous or aqueous-methanolic) medium. Elemental analysis, visible and IR data for the complexes are also obtained.
