Summary
The synthesis of a new series of 14- and 16-membered hexaazamacrocyclic complexes has been achieved by the template condensation of ethylenediamine or 1,3-propylenediamine with formaldehyde and acetamide in a 1∶2∶1 molar ratio in the presence of metal chlorides. Octahedral structural formulae for selective metal complexes are proposed on the basis of physico-chemical and spectroscopic data. The redox behaviour in DMSO solution of the CuII complexes has been studied by cyclic voltammetry.
