Annotation	Square planar palladium(II) aryl-amido complexes of diphosphinoazines in monoanionic unsymmetrical PNP pincer-type coordination were prepared by reactions of phenyl-, o-tolyl-, or 2,6-dimethylphenyllithium with previously described chloro-amido complexes of diphosphinoazines having isopropyl, cyclohexyl and tert-butyl substituents on phosphorus atoms. The compounds were characterized by NMR showing free rotation around metal-aryl bond in the complexes; the presence of Cipso – Pd bond was detected by two-dimensional experiments. In addition to that, crystal and molecular structure of two complexes was determined by x-ray diffraction. In both structures the ligand trans to the amide nitrogen is well surrounded by substituents on phosphorus atoms, the phenyl complex showing significant interactions between two cyclohexyl hydrogen atoms and the pi-system of the phenyl ring.
