N2 - A possibility of generating spin polarization of 19F nuclei in the counterions that form no covalent bond with the metal center is shown for the first time for new iridium complexes synthesized by reversible binding with the substrate (pyridine) and parahydrogen. This makes it possible to observe the integral polarization of 19F nuclei in weakly coordinated tetrafluoroborate and hexafluorophosphate anions. The optimum parameters of the magnetic field strength for the maximum amplification of the 19F signal in two fluorine-containing anions are determined from the dependences of the signal intensity in the NMR spectra on the magnetic field strength for two synthesized iridium complexes.
