7.  Mononuclear Complex of Fe(III) with N, Ní-tetra(4-antipyryl-methyl)-1,2 diaminoethane. Synthesis and Spectral Properties

Authors: Elena-Maria Mosoarca, Ramona Tudose, Wolfgang Linert, Otilia Costisor


Abstract:

The synthesis and spectral properties of a new mononuclear complex of Fe(III) containing the Mannich base N,Ní-tetra(4-antipyryl-methyl)-1,2diaminoethane (TAMEN) as ligand, [Fe(TAMEN)](ClO4)3⋅6H2O are presented. The molar conductivity value of iron(III) complex recorded in DMF solution, shows the 1:3 electrolyte type behavior, proving that the perchlorate anion not coordinate to the central metal ion. The electronic and IR spectra have revealed that the ligand acts as a hexadentate one through the two nitrogen atoms of ethylenediamine bridge and the four oxygen atoms of the antipyrine fragments.


Keywords: mononuclear complex, antipyrine, iron(III), ethylenediamine
