new type of tetradentate ligand has been synthesized by bridging two molecules of N,N'-diisobutyl-2,3-dimercaptosuccinamide with N-(3-aminopropyl)propane-1,3-diamine. The resulting stereoisomeric tetrathiolato S(4) ligand of composition ((i)()Bu)(2)N(O)C-C(SH)-C(SH)-C(O)NH-(CH(2))(3)-NH-(CH(2))(3)-NHC(O)-C(SH)-C(SH)- C(O)N((i)Bu)(2) forms anionic five-coordinate oxorhenium(V) complexes by a ligand-exchange

The aim of the invention is to provide radiolytically and metabolically stable metal complexes suitable for conjugation with biomolecules and, therefore, useful for nuclear medical diagnostics and in endoradionuclide therapy and to provide a method for their production. This is achieved by metal complexes based on tetrathiol ligands of formula (I), in which (CH—R
