摘要：

The Ni2+-glycine-L-histidine system in aqueous solution at 298.15 K and ionic strengths of 0.2, 0.5, and 1.0 with potassium nitrate as the supporting electrolyte has been investigated calorimetrically. Standard thermodynamic characteristics (Delta(r) HA degrees, Delta(r) GA degrees, Delta(r) SA degrees) of complexation have been determined. The NiLY complex is highly stable with respect to decomposition into homoligand complexes.
