Iron(III) complexes on the basis of azomethine derived from 4,4′-dodecyloxybenzoyloxybenzoyl-4-oxy-2-hydroxybenzaldehyde

This work deals with the synthesis and investigation of phase behavior of iron(III)-containing complexes of linear azomethine derived from 4,4'-dodecyloxybenzoyloxybenzoyl-4-oxy-2-hydroxybenzaldehyde with NO (3) (-) , PF (6) (-) , Cl(-), and BF (4) (-) counterions. All semiproducts and target substances are characterized by TLC, elemental analysis, IR and NMR spectroscopy, and melting points. It is established that the reaction of Schiff base with metal salts at room temperature leads to the formation of complexes having presumably the linear structure. Phase behavior of the compounds obtained depending on the nature of counterion was studied.
