摘要

Dibenzo[e,k]-2,3-bis(hydroxyimino)-1,4-dithia-7,10-diaza-2,3,8,9-tetrahydr ocyclododecine (H(2)L) has been prepared from 1,2-bis(o-mercaptoanilino) ethane (4) and (E,E)-dichloroglyoxime. A mononuclear complex with a metal: ligand ratio of 1:2 has been isolated for cobalt(III). The Co-III complex of H(2)L has been prepared with L' = 2,6-lutidine, and with a chlorine ion as axial ligands. In addition to that, the synthesis of a new cobalt complex which contains BF2+ bridges is achieved with the bis(E,E)-dioxime ligand. The trinuclear complex of this Co-III complex has been obtained by the reaction of BF2+ bridged Co-III complex with Pd[bis(benzonitrile)]Cl-2. The structures of these complexes and (E,E)-dioxime were identified by using elemental analysis, H-1 and C-13-NMR, IR and MS spectral data. [References: 44]
