The formation of two complexes by reaction of [PdCl4](2-) with 1,2,3-triphe
nylguanidine (PhNH)(2)C=NPh under different metal/ligand ratios has been ob
served and the structure of the complex [(1,2,3-triphenylguanidine)(2)PdCl2
] has been determined by X-ray diffraction methods. The ligands are coordin
ated as neutral monodentate molecules to the metal centre through their imi
ne nitrogen atoms. The second Pd(II) complex is [Pd(1,2,3-triphenylguanidin
e)(4)](2+) and was isolated by precipitation with ClO4-.
