A simple synthetic procedure (reaction between Re(CO) 5Cl and 2-[( E)-(phenylimino)methyl]- or 2-[( E)-( n-propylimino)-methyl]-phenol) leads to novel dimeric Re 2(CO) 6(N∩O −) 2 complexes with the structures confirmed by means of X-ray crystallography. The obtained species have been characterized by means of elemental analysis, FT-IR, UV–VIS absorption, and EI-MS spectroscopy. The solvolysis experiments performed in dimethylsulfoxide solutions point to well pronounced stability of the investigated species. A simple procedure (reaction in boiling toluene between Re(CO) 5Cl and Schiff base ligands LH synthesized from salicylic aldehyde and alkyl or aryl amines) leads to novel center-symmetric dimeric complexes Re 2(CO) 6(L −) 2. [Display omitted] ► Schiff base derivatives of salicylic aldehyde LH react with Re(CO) 5Cl with formation of dimeric species with general formula of Re(CO) 6(L −) 2. ► The synthesized complexes have been characterized using EI-MS, UV-VIS, and IR spectroscopy. ► Centre-symmetric structures of the investigated complexes have been confirmed by means of X-ray investigations.
