exists as a chelate complex 5. The ligands NN = 2–4 form complexes in the solid state with either macrocyclic structures [Ag2(μ-NN)2]X2 [6, NN = 2, X = BF4; 9, NN = 3, X = NO3] or polymeric structures [7, NN = 2, X = NO3; 8, NN = 3, X = CF3CO2; 10, NN = 4, X = CF3CO2]. The ligands 2 and 3 gave both macrocyclic and polymeric complexes, depending on the anion. In solution, these complexes existed as mixtures
