N2 - This paper describes a new type of asymmetrical Fe(III) complex, containing two different ligands in the equatorial and axial positions: (i) a double-donor organometallic asymmetrical cis-N2O2 Schiff base ligand and, (ii) a 4-bromophenolato ligand, respectively. The synthesis and full characterization of the compound show a pentacoordinated environment for Fe(III) ion. X-ray analysis reveals that the title compound has a distorted square base pyramid geometry with a centrosymmetric crystal packing. According to the electrochemistry and the electronic absorption spectra results, the new complex is a promising building block for the construction of dipolar D–π–A systems in the field of optoelectronic devices.
