1,1-Diamino-2,2-dinitroethene FOX-7 reacts readily with copper nitrate in an aqueous solution of potassium hydroxide to form pea green CuFOX2H2O2 5. FOX-7 complexes of copper and nickel supported by a variety of diamines including Cu- en2FOX2H2O 1, Cupn2FOX2 2, CubipyFOX2H2O4 3a, Cu- bipy2FOX2H2O2 .5 3b, CubipyFOX2DMSO2 2DMSO 3c, Cu- phen3FOX2H2O3 4, Ni2phen6FOX4NO33H2O2 6, and Ni- bipy3FOX2H2O4 7a were obtained via metathesis reactions with potassium-FOX KFOX. Surprisingly FOX-7, in the presence of NiII and bipyridyl in a mixed solvent of methanol and dimethyl sulfoxide, gave a chelated FOX carbamate anion resulting in the compound Nibipy2FOX CO2 DMSO 7b. All metal salts were characterized by infrared, elemental analysis, and differential scanning calorimetry DSC. Single-crystal X-ray diffraction structures were obtained for compounds 1, 2, 3c, 6, and 7b.
