Synthesis, characterization, and crystal structures of Cu, Ag, and Pd dinitramide salts

Abstract

The literature known, but not fully characterized, silver dinitramide transfer reagents AgN(NO2)2 (1), [Ag(NCCH3)][N(NO2)2] (2), and [Ag(py)2][N(NO2)2] (3) have been investigated by 109Ag, 14N NMR and vibrational spectroscopy (IR, Raman). In addition, the poorly understood [Cu(NH3)4][N(NO2)2)]2 (4) and [Pd(NH3)4][N(NO2)2]2, (5) have also been prepared and characterized by 14N NMR and vibrational spectroscopy (IR, Raman). The structures of 2-5 have also been determined by X-ray diffraction.
