【摘要】 使用RD-1型热导式自动量热计分别测定了Ni(Ⅱ)-N-(对位取代苯基)氨基乙酸和Ni(Ⅱ)-N-(间位取代苯基)氨基乙酸的配位热,发现在配位热与配体的质子化热之间存在直线焓关系:△H_M=A-B△H_L,此外,在配位熵与质子化熵之间亦存在线性关系。更多还原

【Abstract】 The heats of formation of complex compounds Ni(Ⅱ)-N-(substituted phenyl) glycines were determined by means of RD-1 model conduction automatic calorimeter at 25℃ in 30%(V/V) ethanol solution in the presence of NaClO4(0.1 mol·dm-3). Linear enthalpy relationships between the heat of formation of complex compounds and the heat of protomation of ligands were again found to exist in these binary systems which conform nicely to the equation:ΔHM=A-BΔHL.In addition, linear entropy relationships between the entropy of formation of complex compounds and the entropy of protonalion of ligands were also found to exist in these binary systems.更多还原
