β¦ Synopsis
Copper(H) acctatc was calorimetrically titrated with pyridine , I-. 3-and 4-mcthylp~ridinc in absolute ethanol. The enthalpy of reaction and the equilibrium constant were determined for the adduct fornxttion in solution for each ligand. The aminci react with copper(H) acetate without breaking the dimcric structure at least in the limit of the concentration ratiolligandI/I(CH3C0,),Cu,I<:.

Proton relaxation and lme shifts have been studied in solutions of copper acetate. The relaxing power of the acetate tier spm trmlet is much less than that of the monomer molecule or the Cu IOAS. Exchange contrlbutes to T2. \_
## Abstract Four new ligands, namely the Nβsubstituted 2β(4βsulfonyl)βpyrrylmethyl derivatives of methylamine, glycine, ethylenediamine and iminodiacetic acid, were synthesized to investigate the coordinating tendency of pyrrolic nitrogen in aqueous solution. The complex formation of these ligands
