Abstract

In this study, a novel (E,E)-dioxim containing a diazatetrathiadioxa macrobicyclic moieties (19E, 20E)-6,7,14,15,18,21,24,25-oktahydro-13,26-(ethanothioethano-thioethano)dibenzo[14,15:8,9]-[1,4,10,13,7,16]dioxadithiadiazacyclooctadecino[2,3-g] quinoxaline- 19,20,27,34-tetrone 19,20-dioxime (H2L) has been synthesized by reacting cyanogen-di-N-oxide with 2,3-diamino-6,7,14,15,22,23-hexahydro-8,21-(ethanothioethanothioethano)tribenzo[b,h,n][1,4,10, 13,7,16]dioxadithiadiazacyclooctadecine-25,32-dione (8), which was prepared by the reduction of 2,3-dinitro-6,7,14,15,22,23-hexahydro-8,21-(ethanothioethanothioethano)-tribenzo[b,h,n] [1,4,10,13,7,16]dioxodithiadiazacyclooctadecine-25,32dione (7). The macrobicyclic (7) was synthesized by the condensation reaction of compound (5) with compound (6) in the presence of the Na2CO3 under an argon atmosphere in the refluxing acetonitrile. Mononuclear complex (11) with metal:ligand ratio 1:2 of this ligand has been synthesized by reacting the vic-dioxime (H2L) with NiCl2.6H2O. The new compounds were characterized by a combination of elemental analysis, 1H- and 13C-NMR, IR and MS spectral data.
