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

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 Ag-109, N-14 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 N-14 NMR and vibrational spectroscopy (IR, Raman). The structures of 2-5 have also been determined by X-ray diffraction.
