O}n (2a) were synthesized from an identical starting mixture with 2-(carboxyphenyl)iminodiacetic acid (H3cpida) and 1,10-phenanthroline (phen) at 5 °C and 25 °C, respectively. Additionally, complexes 2b–2d, which are isostructural to 2a, were obtained using Cu(ClO4)2, Cu(BF4)2, and Cu(CF3SO3)2 instead of Cu(NO3)2 in the temperature range 0–65 °C. 1 is characterized by a V-shaped trinuclear CuII monomer
以Cu(NO3)2为金属盐,[Cu3(cpida)(phen)2(H2O)5]·3NO3·2H2O(1)和[Cu2(cpida)(phen)(NO3)]·2H2O}n( 2a) 分别在 5 °C 和 25 °C 下由相同的起始混合物与 2-(羧基苯基) 亚氨基二乙酸 (H3cpida) 和 1,10-菲咯啉 (phen) 合成。此外,在 0-65 °C 的温度范围内,使用 Cu(ClO4)2、Cu(BF4)2 和 Cu(CF3SO3)2 代替 Cu(NO3)2 获得了与 2a 同构的配合物 2b-2d . 图1的特征是V形三核CuII单体,而2a-2d的特征是一维(1D)ΔCuII链。在 1 中观察到由硝酸根阴离子构建的大量氢键。进行了结构转化研究,发现 1 可以在 25°C 下从反应溶液完全转化为 2a,温度在该过程中起着至关重要的作用。
