配合物的生成热与配体的质子化热之间的直线焓关系——Ⅶ. 镍(Ⅱ)-2,2′联吡啶-N,N′-双(对位取代苯基)乙二胺的二元及三元体系
摘要:
使用MS 80型Calvet微量热计, 在25 ℃, 0.1mol·dm~(-3)(NaClO_4)的50%(V/V)二氧六环溶液中, 测定了镍(Ⅱ)-N,N′-双(对位取代苯基)乙二胺二元及镍(Ⅱ)-2,2′-联吡啶-N,N′-双(对位取代苯基)乙二胺三元体系的生成热和N,N′-双(对位取代苯基)乙二胺的质子化热, 发现在二元和三元配合物的生成热、生成熵与配体的质子化热及质子化熵之间存在较好的线性关系。

LINEAR RELATIONSHIPS BETWEEN THE HEATS OF FORMATION OF COMPLEX COMPOUNDS AND THE HEATS OF PROTONATION OF LIGANDS——VII Ni(II)-N,N′-BIS (para-SUBSTITUTED PHENYL) ETHYLENEDIAMINE BINARY AND Ni(II)-BIPY-TERNARY SYSTE
Abstract:
The heats of protonation of N, N′-bis (p-substituted phenyl) ethylenediamine (R=CH_3O; CH_3; H; CI) and the heats of formation of their binary and ternary complex compounds with Ni(Ⅱ)-and Ni(Ⅱ)-bipy-respectively, were determined by MS-80 Calvet microcalorimeter at 25 ℃ and I=0.1 mol·dm~(-3) (NaClO_4) in 50% (V/V) dioxane solution. The linear enthalpy relationships between the former and the latter was found again. In addition, the linear entropy relationships between also the entropies of protonation and of formation of binary (or ternary) system were also found to exist.
