Syntheses of the first Cu(NH3)(2)(FOX)(2) and various Cu(amine)(2)(FOX)(2) (methyl, propyl, and dimethyl amine) complexes were achieved by using metathetical reactions which add a new chapter to the metal chemistry of FOX-7 (1,1-diamino-2,2-dintroethene). The crystal structures of Cu(NH3)(2)(FOX)(2) and Cu(C3H7NH2)(2)(FOX)(2) which show square planar geometry at copper aid in the understanding of the bonding modes in FOX-7 copper complexes which is supported by natural bond orbital (NBO) calculations. Water-free K-FOX was also structured.
