Abstract
The structures of high-spin iron(III) complexes with poly(propylenimine) dendrimers were examined by EPR spectroscopy. The pseudotetrahedral distortion of the coordination unit (CU) was considered. The fine structure parameters (FSPs) of the EPR spectra were analyzed. A dependence of the FSPs on the CU distortion and the covalent bonding was established. The influence of the axial Cl atoms on FSPs was considered. Splitting of the quartet term caused by the orthorhombic CU distortion with a pseudotetrahedral structure was estimated from the EPR data.
