Abstract
A new vicinal dioxime ligand containing bis(diazadioxa-12-crown-4 ethoxy) units (H2L) has been synthesized by the reaction of cyanogendi-N-oxide with 3,4-bis(2-{10-[(4-methylphenyl)sulfonyl]-1,7-dioxa-4,10-diazacyclododecan-4-yl}ethoxy)aniline, which was prepared by the reduction of 4-[(4-methlyphenyl)sulfonyl]-10-[2-((4-nitro-2-{2-[10-phenylsulfonyl)-1,7-dioxa-4,10-diazacyclododecan-4yl]ethoxy}phenoxy)ethyl]-1,7dioxa-4,10-diazacyclododecan. A mononuclear nickel(II) and copper(II) complexes with a metal:ligand ratio of 1:2 for H2L were also synthesized. The mononuclear cobalt(III) complex of H2L has been isolated with L 0 = pyridine, together with chlorine as an axial ligand. In addition, a cobalt(III) complex containing the BF2 þ bridge macrocycle was synthesized using a pre
