• Resumen

  • A series of {H3O+}[MQs4]− (M=Tb, Eu, Lu; HQs=1-phenyl-3-methyl-4-thenoylpyrazole-5-one) complexes have been prepared and characterized; the presence of the {H3O+} cation stabilized by H-bonding to the pyridinic nitrogen of Qs has been confirmed by X-ray and spectroscopic (NMR, IR) investigations.
