Abstract

The invention relates to new fluorine-containing macrocyclic metal complexes that consist of a complexing agent of formula I and at least one metal ion of an element of atomic numbers 21-29, 42, 44 or 57-83 ##STR1## in which n, R.sup.1, R.sup.2, R.sup.3 and A have a different meaning, agents containing these compounds, their use as NMR and x-ray diagnostic agents as well as process for the production of these compounds and agents.
