| Abstract: | The diamide ligand, 2,6-bis[(N-phenyl)amido]-4-methylphenol (HL), has been used to synthesize a mononuclear iron(III) complex [Fe(L)3]·DMF and characterized by elemental analyses, IR, UV–vis spectroscopy, cyclic voltammetry and finally by X–ray crystallography. X-ray diffraction analysis reveals that the complex crystallizes in the triclinic space group P-1(2) with a = 12.4923(15) Å, b= 13.5095(16), c = 19.296(2) Å, α = β = 86.451(2)°, γ = 66.5850(10)°, V = 2980.1(6) Å3 and Z = 2 with the central iron(III) ion in distorted octahedral geometry. The complex shows extensive intra- and intermolecular hydrogen bonding between each molecular units as well as solvent molecules giving rise to a two dimensional assembly. It also exhibits intermolecular π–π interaction between the aromatic rings with centroid distances of around 3.55 Å. In cyclic voltammetric studies, the iron(III) complex exhibits one quasi-reversible reduction at E1/2 = +0.046 V versus Ag/AgCl (ΔEp = 0.092 V) due to a metal-centreed FeIII/FeII reduction. |
