文摘

The reaction of triethylindium with salicylaldehyde–aroylhydrazone, C₆H₄(o-OH)ges/glyphs/BO7.GIF>CHNNHges/glyphs/BO7.GIF>C(O)C₆H₄ges/glyphs/BO7.GIF>X (X=p-H, p-OCH₃, p-NO₂, m-NO₂, o-OH), yields the tetrahydrofuran (THF) adduct of (C₁₄H₉N₂O₂X)₂InC₂H₅. With formylferrocenyl–aroylhydrazones C₅H₅FeC₅H₄ges/glyphs/BO7.GIF>CHNNHges/glyphs/BO7.GIF>C(O)C₆H₄ges/glyphs/BO7.GIF>X (X=p-H, p-OCH₃, p-NO₂, m-NO₂, p-Cl, o-Cl), the diethylindium–hydrazone complex, (C₁₈H₁₄N₂OFeX)In(C₂H₅)₂, was formed. With salicylaldehyde–ferrocenoylhydrazone, C₆H₄(o-OH)ges/glyphs/BO7.GIF>CHNNHges/glyphs/BO7.GIF>C(O)C₅H₄FeC₅H₅, the monohydrazone complex (C₁₈H₁₅N₂O₂Fe)In(C₂H₅)₂ tetrahydrofuran solvate was obtained. The crystal structures of the p-OCH₃ derivatives of the first two series of complexes and of the ferrocenoylhydrazone derivative were determined. In the solid state, the three complexes are dimers, containing a set of seven, three and five fused rings, respectively. In every case, it was observed a symmetric anti arrangement of fused rings in relation to a central In₂O₂ four-membered ring, resulting in a configuration that resembles a chair. Cyclic voltammetric studies on the ferrocenylaroylhydrazone complexes revealed electron transference from the ferrocene group towards the indium atom, while for the salicilaldehyde–ferrocenoyl complex this was not observed.
