Аннотация:Clathrochelate iron(II) FeBd(2)(S2C2(CN)(2)Gm)(BF)(2) tris-dioximate with a ribbed vic-dinitrile fragment was synthesized as a precursor of the monoribbed-functionalized hybrid phthalocyaninoclathrochelates by nucleophilic substitution of the vic-dichloride FeBd(2)(Cl(2)Gm)(BF)(2) clathrochelate (1) with the potassium salt of dimercaptomaleodinitrile. Reaction of nitromethane with this salt was followed by the condensation of the reaction products with 1 to yield the clathrochelate with an annulated previously unknown thiazinothiophene heterocyclic system in the ribbed fragment. Both complexes were characterized on the basis of elemental analysis; MALDI-TOF mass spectrometry; IR, UV-vis, Fe-57 Mossbauer, and NMR spectroscopies; and X-ray crystallography.
