New palladium(II) complexes containing the water soluble aminophosphine PTN ligand (PTN = 7-phospha-3,7-dimethyl-1,3,5 triazabicyclo[3.3.1]nonane) in 1:1 and 1:2 ratio Pd/PTN ligand, respectively, were prepared and fully characterised by mono and bidimensional 31P, 1H and 13C NMR techniques showing that PTN can adopt both j1-P and j2-P,N coordination modes. The complexes with Pd/PTN ratio 1:2 arehighly soluble in water at room temperature. Suitable crystals for X-ray structure determination were obtained for the neutral complex k2-P,N-Pd(PTN)(OAc)2 (1) and for the monocationic complex [Pd(k2-P,N-PTN)(k1-P-PTN)Cl][PF6] (5).

Abstract
New palladium(II) complexes containing the water soluble aminophosphine PTN ligand (PTN = 7-phospha-3,7-dimethyl-1,3,5 triazabicyclo[3.3.1]nonane) in 1:1 and 1:2 ratio Pd/PTN ligand, respectively, were prepared and fully characterised by mono and bidimensional 31P, 1H and 13C NMR techniques showing that PTN can adopt both j1-P and j2-P,N coordination modes. The complexes with Pd/PTN ratio 1:2 arehighly soluble in water at room temperature. Suitable crystals for X-ray structure determination were obtained for the neutral complex k2-P,N-Pd(PTN)(OAc)2 (1) and for the monocationic complex [Pd(k2-P,N-PTN)(k1-P-PTN)Cl][PF6] (5).| File | Dimensione | Formato | |
