Thermodynamic constants for the formation of silver complexes of some saturated and unsaturated (alkylthio) and (alkylseleno)acetic acids have been calculated by measuring formation constants over the range 0–40° at /= 0·20M. In particular, co-ordination to silver through an olefinic double bond has been shown to have a large favourable enthalpy change, strongly opposed by entropy changes. An analysis
通过在/ = 0·20 M范围内在0–40°范围内测量形成常数,可以计算出一些饱和和不饱和(烷硫基)和(烷基硒代)乙酸的银络合物形成的热力学常数。特别地,已经表明通过烯属双键与银的配位具有大的有利的焓变化,强烈地受到熵变化的阻碍。对实验数据的分析表明存在复合物Ag 2 L,AgL和AgL 2。描述了用于处理复合物的计算方法。
