| 摘要: 使用RD-1型热导式自动量热计,在25℃,Ⅰ=0.1M,30%(V/V'乙醇的条件下,分别测定了镍(Ⅱ)-邻菲啰啉-N-(对位取代苯基)氨基乙酸和锌(Ⅱ)-邻菲啰啉-N-(对位取代苯基)氨基乙酸三元配合物的生成热。应用前文中所报告的N-(对位取代苯基)氨基乙酸的第一级质子化热数据与之对画作图,可以得到相关系数Γ在0.99以上的两条直线,这就再一次验证了直线焓关系的存在。此外,我们还计算了三元配合物的生成熵并和N-(对位取代苯基)氨基乙酸的第一级质子化熵相关联,也得到了较好的线性关系。 |

| Abstract: The heats of formation of ternary complex compounds from nickel (I)or zinc(I) with 1,10-phenanthroline and N-(para-substituted phenyl) gly-cines have been determinated by calorimetric method at 25℃ and I = 0.lM(NaClO4) in 30%(V/V) ethanol solution. To quote the heats of protonationof N-(parasubstituted phenyl) glycines in previous paper and to plot them vs. the heats of formation of ternary complex compounds, two straight lines were can be obtained, with appraximately the same negative slope value.The existence of linear enthalpy relationship in ternary complexes system have been verified once again experimentally. In addition, linear entropy relationships between the entropy of formation of ternary complex compound and the entropy of protonaliou of the second ligand have been found.The significance of these linear relationships have been discussed in terms of CFSE and bach π bonding formaiton. |
