Palladium(II) complexes of 1,10-phenanthroline: Synthesis and X-ray crystal structure determination

Two palladium(II) complexes, [Pd(phen)(NCCH3)2][O3SCF3]2 (1) and [Pd(phen)(μ-OH)]2[O3SCF3]2 · 2H2O (2) (where phen = 1,10-phenanthroline), have been crystallized following the reaction of Pd(phen)Cl2 with silver triflate, Ag(O3SCF3), in acetonitrile and water, respectively. The structures of both complexes are based on a Pd(phen)2+ metal core, with two acetonitrile molecules binding in a monodentate fashion in complex 1 and two hydroxo bridges holding together two cores to form a dimer in complex 2. Additionally, both complexes present a hydrogen bonded 3-D network involving the triflate anions in 1, and water and triflate anions in 2. Both complexes have been characterized by infrared and 1H NMR spectroscopy and their crystal structures determined by X-ray crystallography.
