Özet

A novel bis(dioxime) (H4L) containing the hexaoxa macrocyclic moiety has been synthesized from the reaction of tetraaminodibenzo-18-crown-6 (1) and 2,3-butanedione monooxime (2). An octahedral cobalt(III) complex of this ligand was prepared by the oxidation of the cobalt(II) complex. The BF2 bridged cobalt(III) complex was achieved by using the hydrogen bridged cobalt(III) complex and boron trifluoride. The structures of the bis(dioxime) and its complexes are proposed according to elemental analysis, H-1 and C-13 NMR, IR and MS data.
