This invention relates to new bifunctional chelating agents with intermittent chalcogen atoms, pharmaceuticals containing these compounds, their use in radiodiagnostics and radiotherapy, and methods for the production of these compounds. The compound according to the invention has the general formula (I) M--L where M represents a radionuclide and L a ligand of the general formula (II). It was found, surprisingly, that these new, bifunctional chelating agents with intermittent chalcogen atoms and their coupling products with compounds that accumulate specifically are excellently suited for producing radiopharmaceuticals for diagnostic and therapeutic purposes.
