Synthesis, characterization and properties of iron(II) complexes with a series of tripodal ligands based on the parent ligand tris(2-pyridylmethyl)amine
摘要:
Iron(II) complexes of the type [Fe(L)(NCS)(2)] with the tripodal ligand apme (apme = N-1-(2-aminoethyl)-N-1-(2-pyridyl-methyl)-1,2-ethanediamine) as well as with its derivatives were prepared and structurally characterized. The bond distances thus obtained showed that all complexes investigated were high-spin at the respective temperature. Furthermore [Fe(Me(4)apme)(NCS)(2)] was analyzed using Mossbauer spectroscopy that showed that this complex remains in its high-spin state over the entire temperature range. (C) 2011 Elsevier B. V.
