Abstract
We synthesised a series of seven mononuclear Schiff base coordination compounds. The symmetric pentadentate N3O2-donating ligands were prepared by the condensation of N-(2-aminoethyl)-1,2-ethanediamine with either 5-bromosalicylaldehyde or 5-chlorosalicylaldehyde. The octahedral coordination sphere is completed by different pseudohalide mondentate N-donating ligands. All complexes have been analysed by Mössbauer spectroscopy, ESI-MS and IR spectroscopy. The Mössbauer spectra at room temperature reveal a doublet, which are related to the high spin state (S = 5/2) of the iron(III) centres.
