Abstract

Iron(II) complexes of the type [FeL2X2] (L=bidentate ligand, X=H2O, Cl, or SCN) and [FeL2] (L=tridentate ligand) with polydentate ligands derived from 2-(acetylamino)benzoic acid, 2-(benzoylamino)benzoic acid,2-[2-aminobenzoylamino]benzoic acid, 2-[amino-carbonyl]benzoic acid, 2-[(phenylamino)carbonyl]-benzoic acid, 2-[aminobenzoyl]benzoic acid and 2-aminobenzanilide have been synthesized and characterized by elemental analyses, conductivity, magnetic susceptibility and i.r., electronic, n.m.r., and Mossbauer spectral studies. The different modes of ligand chelation and the stereochemistry around the metal ion are discussed. The small range of isomer shift values for iron(II) complexes confirms the similar geometry for all the complexes.
