使用改进的ＲＤ—１型热导式自动量热计测定了Ｎｉ（Ⅱ）、Ｃｏ（Ⅱ）、Ｚｎ（Ⅱ）－Ｎ－（间位取代苯基）亚氨基二乙酸三个二元体系的表观生成热．当将其与它们的配体的质子化热相关联时，发现在两者之间存在着良好的直线焓关系．这些金属离子配合物的生成热也符合Ｉｒｖｉｎｇ—Ｗｉｌｌｉａｍｓ序列，即有Ｃｏ（Ⅱ）＜Ｎｉ（Ⅱ）＞Ｚｎ（Ⅱ）的顺序．配体上取代基不同，其生成热的大小有Ｃｌ－＞ＣＨ３Ｏ－＞Ｈ－＞ＣＨ３－的顺序．从两级生成热来比较，有一级大于二级的普遍规律．本文详细地讨论了这些规律．
The binary systems of Ni (Ⅱ), Co (Ⅱ), Zn (Ⅱ) -N- (meta-substituted phenyl) iminodiacetic acid Apparent heat of formation. When it was correlated with the protonation heat of their ligands, it was found that there was a good linear enthalpy relationship between the two. The heat of formation of these metal ion complexes is also in accordance with the Irving-Williams sequence, namely the order of Co (II) Zn (II). Ligands on different substituents, the heat generated by the size of Cl-> CH3O-> H-> CH3- order. Generated from the two heat to compare, there is a general rule of two levels greater than two. This article discusses these rules in detail.
