We report here the straightforward synthesis of some d-block metal dimers of a Schiff base ligand obtained by condensation of 2‑tosylaminomethylaniline with  4-formyl-3-hydroxybenzoic acid (H₂L). The easy bideprotonation of both -OH and ‑HNSO₂- groups, as well as a suitable N,N,O binding domain that can simultaneously bind two metal ions through µ₂-N_sulfonamido bridges have been considered during the design step of the Schiff base ligand. All the compounds synthetised were characterised by a combination of ¹H NMR spectroscopy, infrared spectroscopy, mass spectrometry and elemental analysis. We have used 2‑D NOESY spectra of some of the compounds for structure elucidation in solution.
