Investigation of the homonuclear and polynuclear complexes of FeIII of pentadentate dipodal s-triazine Schiff base ligand

An efficient synthesis of a new class of “Dipodal s-triazine Schiff base ligand” has been developed based on high-yielding amines substitutions of 2-vinyl-4,6-diamino-1,3,5-triazine (acryloguanamine) (VDAT) by salicylaldehyde. A new compound characterized by a dipodal s-triazine pentadentate Schiff base with 2-vinyl-4,6-N,N’-bis(2,4-dihydroxybenzylidine)-1,3,5-triazine [VDAT24] has been developed. The obtained [VDAT24] was polymerized to obtain poly(2-vinyl-4,6-N,N’-bis(2,4-dihydroxybenzylidine)-1,3,5-triazine) [PVDAT24]. Subsequently, s-Triazine-centered Fe(III) homonuclear complexes [VDAT24Fe], and polynuclear complexes [PVDAT24Fe] were obtained derived. As a result, the ligand obtained by elemental analysis, ICP-AES, TGA, FTIR, ¹H NMR and ¹³C NMR. Isolated ligand complex, FTIR, TGA, and were illuminated structures on the magnetic susceptibility. The resulting two different polymeric ligands and certain complexes of FTIR, TGA, and Ostwald Viscometer elucidated the structures of magnetic susceptibility.
