✦ Synopsis

The formation of complexes of Co(I1) with adenosine monophosphoric (AMP) and adenosine diphosphoric (ADP) anions have been studied by pH-stat and pH variable potentiometry and also by calorimetry. The existence. of complexes of type ML (CoAMP and CoADP-), MHL (CoHADP) and ML2 [Co(ADP)z-] is in good agreement with the experimental results. The stability constants of formation of these complexes as well as their corresponding thermodynamic values, obtained in an 0.2 M solution of tetramethylammonium bromide, are presented in the Tables 1, 2 and 3.
