By utilizing the formation constants of Ni(Ⅱ)-Glycine binary complex compounds and the corresponding heats of formation from literature as well as the formation constants of Ni(Ⅱ)-Oxalate binary complex compounds and the corresponding heats of formation incorporating with the formation constants of Ni(Ⅱ)-Oxalate-Glycine competitive ternary complex compounds determined in our laboratory, the heats of formation of Ni(Ⅱ)-Oxalate-Glycine competitive ternary complex compounds have been determined at 25 ℃, I=0.1 mol·dm~(-3) (KNO_3) in aqueous solution by means of RD-1 model automatic conduction calorimeter. The results obtained are:ΔH_(AB)~M=-14.3±2.0 kJ·mol~(-1)ΔH_(A2B)~M=-27.0±2.0 kJ·mol~(-1)ΔH_(AB2)~M=-40.2±2.0 kJ·mol~(-1)
