Abstract

This paper reports on the inorganic sonochemical synthesis of crystalline Ni(C₄H₆N₂)₆(PF₆) ₂, Fe(C₄H₆N₂)₆(BF ₄)₂, and Ni(C₄H₆N₂) ₆(BF₄)₂ in the ionic liquids, 1-butyl-3-methylimidazolium hexafluorophosphate (BMI)₊(PF ₆)^- and 1-butyl-3-methylimidazolium tetrafluoroborate (BMI)⁺(BF₄)^-. The structures of the compounds were determined and refined by using powder X-ray diffraction methods. The salts crystallize in the trigonal P3̄ space group. IR, Raman and ¹⁹F NMR spectroscopic studies confirm that the PF₆^- and BF₄^- anions are not bonded to the metal cations. Magnetic measurements reveal the paramagnetic nature of the complexes. Mössbauer investigations show that the iron atom in Fe(C₄H₆N ₂)₆(BF₄)₂ is in the oxidation +2 state. The broad EPR signals, which reflect the octahedral symmetry of the nickel complexes, were measured for Ni(C₄H₆N ₂)₆(PF₆)₂ and Ni(C₄H ₆N₂)₆-(BF₄)₂.
