Thermodynamic and thermal investigation of Co(II), Ni(II) and Cu(II) complexes with adenine

Complexes of adenine, AdH, with cobalt, nickel and copper chlorides were prepared and their thermodynamic functions were determined. The complexing processes are endothermic in nature. The thermal behaviour of complexes was followed tip by using TG and DTA analyses. The stoichiometry of thermal decomposition of the investigated complexes was suggested.
