Cascade polymer complexes that contain a) complexing ligands of general formula (I), in which A stands for a nitrogen-containing cascade nucleus of base multiplicity a, X and Y, independently of one another, stand for a direct bond or a cascade reproduction unit of reproduction multiplicity x or y, z and W, independently of one another, stand for a cascade reproduction unit of reproduction multiplicity z or w, K stands for the radical of a complexing agent, a stands for numbers 2 to 12, x, y, z and w, independently of one another, stand for numbers 1 to 4, provided that at least two reproduction units are different, and that 16.ltoreq.a.multidot.x.multidot.y.multidot.z.multidot.w.ltoreq.64 holds true for the product of the multiplicities and that at least one of cascade reproduction units X, Y, Z, W stands for a 1,4,7,10-tetraazacyclododecane or 1,4,8,11-teraazacyclotetradecane reproduction unit, b) at least 16 ions of an element of atomic numbers 20 to 29, 39, 42, 44 or 57-83, c) optionally cations of inorganic and/or organic bases, amino acids or amino acid amides as well as d) optionally acylated terminal amino groups are valuable compounds for diagnosis and therapy.
