Interaction of dichloride iron(II) clathrochelate with dimercaptomaleodinitrile: Synthesis of the precursor monoribbed-functionalized phthalocyaninoclathrochelates and the unexpected formation of a new thiophene-containing heterocyclic system in the ribbed chelate fragment of the clathrochelate framework

Clathrochelate iron(II) FeBd₂(S₂C₂(CN) ₂Gm)(BF)₂ tris-dioximate with a ribbed wodinitrile fragment was synthesized as a precursor of the monoribbed-functionalized hybrid phthalocyaninoclathrochelates by nucleophilic substitution of the vic-dichloride FeBd₂(Cl₂Gm)(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, ⁵⁷Fe Moessbauer, and NMR spectroscopies; and X-ray crystallography.
