N2 - A series of PdN4 core complexes has been synthesised. Reaction of [PdCl2(CH3CN)2] with N-alkylaminopyrazole (NN′) ligands, 1-[2-(ethylamino)ethyl]-3,5-dimethylpyrazole (deae), 1-[2-(ipropylamino)ethyl]-3,5-dimethylpyrazole (deai), and 1-[2-(tbutylamino)ethyl]-3,5-dimethylpyrazole (deat) in the presence of AgBF4 led to [Pd(NN′)2](BF4)2. These palladium(II) compounds were characterised by elemental analyses, conductivity measurements, IR, 1H and 13C{1H} NMR spectroscopies. The NMR studies of the complexes prove the rigid conformation of the ligands when they are complexed. The X-ray analyses of one representative complex, [Pd(deat)2](BF4)2, is reported. The crystal structure consists of discrete centrosymmetric cations involving a coordinated Pd(Npz)2(Namino)2 core with planar geometry and multiscripts(BF, 4, mml:none(), mml:none(), -) anions. © 2006 Elsevier B.V.
