The invention relates to new, monomeric, perfluoroalkyl-substituted metal complexes, processes for their production, and their use in diagnosis and therapy. The compounds according to the invention are suitable especially as in vivo contrast media in nuclear spin tomography (MRT). They can preferably be used as blood-pool agents and as lymphographic agents.
