Abstract
The dipodal ligands (Im) and (BIm) as well as complexes [FeLCl3] [L = Im (1) and BIm (2)] have been prepared and studied using spectroscopic techniques. The magnetic moment, IR, electronic (ligand field), FAB-mass and NMR spectral data indicate a hexa-coordinate geometry around high-spin state Fe3+ where the ligands coordinate as a tridentate [N,N,N] chelating agent. 57Fe-Mössbauer spectral data confirmed the presence of a ligand asymmetry around Fe3+ in a high-spin state electronic configuration (t2g3,eg2, S = 5/2) with nuclear transition Fe(±3/2 â ±1/2) exhibiting Kramer's double degeneracy. The molecular computations provided the optimum energy perspective plots for the molecular geometries giving the important structural data.
