Abstract

Abstract Copper (II) azacyclam complexes 3 2+ and 4 2+ were obtained through a metal- templated procedure involving the pertinent open-chain tetramine, formaldehyde and a phenylurea derivative as a locking fragment. Both metal complexes can establish interactions with anions through the metal centre and the amide NH group. Equilibrium studies in DMSO by a spectrophotometric titration technique were carried out to assess ...
