Synthesis and Characterization of a New (E, E)-Dioxime and Its Homo and Heteronuclear Complexes Containing Macrobicylic Moieties

A new N,N'-substituted diaminoglyoxime (H₂L) containing a diazatetraoxamacrobicycle [2.2.2_B] has been synthesized from an aromatic primary amine attached to the cryptand moiety and cyanogen-di-N-oxide. The BF₂⁺-capped Co(III) and heterotri-nuclear complexes of thevic-dioxime were prepared. The new compounds werecharacterized by a combination of elemental analysis and ¹H NMR,¹³C NMR, IR and MS spectral data.
