Abstract
The reaction of Hg(NO3)(2) . H2O with bis(diphenylphosphino)amine, Ph2PNHPP h2 (dppam), produces [Hg-2( HN2O3)(2)(NO3)(2)(dppam)(2)] (1), which is the first complex containing the monoprotonated trioxodinitrate anion. 1 has be en fully characterized by an X-ray structure analysis, NMR spectroscopy (Hg -199{H-1}, P-31(H-1), H-1), FAB mass spectrometry, IR spectroscopy, element al analysis and melting point. 1 is the unique example of a face-to-face co mplex of five-coordinate Hg(II) centres with dppam including the first stru ctural characterization of a rare tautomer of the monoprotonated trioxodini trate anion.
