1,1-Diamino-2,2-Dintroethene (FOX-7) In Copper And Nickel Diamine Complexes And Copper FOX-7

摘要

1,1-Diamino-2,2-dinitroethene (FOX-7) reacts readily with copper nitrate in an aqueous solution of potassium hydroxide to form pea green Cu(FOX)2(H2O)2 (5). FOX-7 complexes of copper and nickel supported by a variety of diamines including Cu- (en)2(FOX)2(H2O) (1), Cu(pn)2(FOX)2 (2), Cu(bipy)(FOX)2(H2O)4 (3a), Cu- (bipy)2(FOX)2(H2O)2 .5 (3b), Cu(bipy)(FOX)2(DMSO)2 2DMSO (3c), Cu- (phen)3(FOX)2(H2O)3 (4), (Ni)2(phen)6(FOX)4(NO3)3(H2O)2 (6), and Ni- (bipy)3(FOX)2(H2O)4 (7a) were obtained via metathesis reactions with potassium-FOX (KFOX). Surprisingly FOX-7, in the presence of Ni(II) and bipyridyl in a mixed solvent of methanol and dimethyl sulfoxide, gave a chelated FOX carbamate anion resulting in the compound Ni(bipy)2(FOX 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.
