Abstract
Two coordination compounds of palladium(II) with N-allylimidazole ((L)) of the general formula [PdL(4)]Cl(2) center dot 3H(2)O (1) and trans-[PdL(2)Cl(2)] (2) have been synthesized. The crystal and molecular structure of complexes 1 and 2 was established by single-crystal X-ray diffraction analysis. The X-ray structural data were supplemented by solid-state (13)C NMR measurements (CP MAS and PASS 2D). The 1D and 2D NMR studies in solution reveal that complex 1 is unstable at room temperature and undergoes reversible decomposition to 2. The method for how to preserve a complex with four allyl-imidazole ligands in solution is shown. (c) 2005 Elsevier B.V.
