Herein, we report the synthesis and characterization of the new di-iron(III) complex (bbpmp)(H2O)(Cl)FeIII(μ-Ophenoxo)FeIII(H2O)Cl)Cl (1), with the symmetrical ligand 2,6-bis{(2-hydroxybenzyl)(pyridin-2-yl)methylaminomethyl}-4-methylphenol (H3bbpmp). Complexes 2 with the unsymmetrical ligand H2bpbpmp — {2-(2-hydroxybenzyl)(2-pyridylmethyl)aminomethyl-6-bis(pyridylmethyl) aminomethyl}-4-methylphenol and 3 with the ligand L1=4,11-dimethyl-1,8-bis{2-N-(di-2-pyridylmethyl)aminoethyl}cyclam were included for comparison purposes. Complex 1 was characterized through elemental analysis, X-ray crystallography, magnetochemistry, electronic spectroscopy, electrochemistry, mass spectrometry and potentiometric titration. The magnetic data show a very weak antiferromagnetic coupling between the two iron centers of the dinuclear complex 1 (J=−0.29cm−1). Due to the presence of labile coordination sites in both iron centers the hydrolysis of both the diester model substrate 2,4-BDNPP and DNA was studied in detail. Complex 1 was also able to catalyze the oxidation of the substrate 3,5-di-tert-butylcatechol (3,5-DTBC) to give the corresponding quinone, and thus it can be considered as a catalytically promiscuous system. The synthesis, X-ray structure and catalytic promiscuity (diesterase and catecholase activity) of a new dinuclear FeIII complex are here reported. Display omitted •Dinuclear Iron(III) complex using a symmetric ligand•Synthesis, X-ray structure, magnetic properties and solution studies of the dinuclear catalyst•Ability of the complex to catalyze different reactions (catalytic promiscuity)
