Synthesis, structure and magnetic characterization of a dinuclear and two mononuclear iron(III) complexes with N,O-donor Schiff base ligands
Abstract One centrosymmetric dinuclear and two mononuclear iron(III) Schiff base complexes, [(µ-OMe)2Fe2(L1)2(N3)2] (1) {HL1 = 2-((2-(dimethylamino)ethylimino)methyl)-6-ethoxyphenol}, [FeL2(OH2)(N3)]·CH3OH (2) {H2L2 = N,N′-bis(3-ethoxysalicylidene)propane-1,3-diamine} and [FeL3(OH2)(NCS)]·2H2O (3) {H2L3 = N,N′-bis(3-methoxysalicylidene)propane-1,3-diamine}, have been synthesized and characterized by elemental analysis and spectral studies. X-ray diffraction analysis was used to determine the structures of all three complexes. Variable temperature (2–300 K) magnetic susceptibility (χ) data of complex 1 show that both iron(III) centres in the complex are in a high spin configuration (S = 5/2)…
Hydrogen bond mediated intermolecular magnetic coupling in mononuclear high spin iron(iii) Schiff base complexes: synthesis, structure and magnetic study with theoretical insight
The crystal structure and magnetic properties of two mononuclear iron(III) Schiff base complexes, [FeL1(NCS)2] (1), HL1 = 2-[1-[[2-[(2-aminoethyl)amino]ethyl]imino]ethyl]phenol and [FeL2(N3)Cl] (2), HL2 = 2-(-1-(2-(2-aminoethylamino)ethylimino)ethyl)-4-methylphenol are reported. Each complex contains a Fe(III) ion surrounded by a N3O Schiff base ligand and two NCS− ligands (in 1) or one N3− and one Cl− ligands (in 2). The magnetic properties can be well reproduced with zero field splittings in the high spin S = 5/2 Fe(III) ions and weak intermolecular Fe–Fe interactions mediated by hydrogen bonds. This intermolecular antiferromagnetic interaction has been validated by using DFT calculations…
