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

Lin Huakuan, Zhu Junying, Gu Zongxin, Chen Rongti*. 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
-
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.
