The water-soluble cobalt(II) tetradentate Schiff base complex Co(II)L(2), L: (N,N'-bis(5-[(triphenylphosphonium)-methyl]salicylidine)-o-phenylenediamineperchlorate has been synthesized and characterized. This complex forms charge transfer (CT) complexes with imidazole and 1-methylimidazole. The formation constant, molar absorptivity (epsilon'), and thermodynamic parameters for charge transfer complexes formation of cobalt(II) Schiff base complexes with imidazole derivatives were determined by using UV-vis spectrophotometric method in aqueous solutions at constant ionic strength (I=0.2mol dm(-3) KNO3) at pH 6.0 and various temperatures between 292 and 315K.
已合成并表征了水溶性钴（II）四齿席夫碱配合物Co（II）L₂，L：（N，N'-双（5-[(三苯基膦基)-甲基]水杨醛缩邻苯二胺高氯酸盐）。该配合物与咪唑和1-甲基咪唑形成电荷转移（CT）配合物。在pH 6.0、离子强度恒定（I = 0.2mol dm⁻³ KNO₃）且温度在292至315K之间的水溶液中，采用紫外可见分光光度法测定了钴（II）席夫碱配合物与咪唑衍生物形成电荷转移配合物的形成常数、摩尔吸光系数（ε'）和热力学参数。
