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.
