neutral bis(ligand)nickel(II) chelates derived from some bidentate aroylhydrazones have been prepared and characterized. Whatever the solubility permits, the reaction of the neutral bis-(ligand)chelates, NiL 2 , with some heterocyclic bases were studied spectrophotometrically in benzene solution. The stability constants as well as the thermodynamic parameters (ΔG, ΔH, ΔS) for the adduct formation reaction
摘要制备并表征了由一些双齿芳酰hydr衍生的阳离子和中性双(配体)镍(Ⅱ)螯合物。无论溶解度如何,均在苯溶液中分光光度法研究了中性双(配体)螯合物NiL 2与一些杂环碱的反应。测量了加合物形成反应的稳定性常数以及热力学参数(ΔG,ΔH,ΔS)。已从吡啶溶液中性双(配体)螯合物的结晶中分离出稳定的固态单,双和四吡啶鎓加合物。
