The reactions of dinuclear palladium precursors with the pyrazolato-bridged bis(imidazolium) salt 3,5-bis(methylimidazolium-1-ylmethyl]-1H-pyrazole bis(hexafluorophosphate) at different conditions are investigated to further explore the scope of this ligand class towards multinuclear complexes. Depending on the reaction conditions, in dichloromethane a dinuclear twofold μ-pyrazolato bridged bis(imidazolium) complex has been selectively synthesized, whereas the corresponding double μ-pyrazolato bridged bis(NHC) complex was obtained when using acetonitrile as solvent. Both complexes were characterized by NMR, elemental analysis and single crystal X-ray diffraction.
