Abstract
Metallacrown complexes capable of sequestering dianions, as shown in the solid state, also exist in aqueous solution at neutral pH, as demonstrated by calorimetric and mass spectrometric data. The driving forces for the formation of these dimeric complexes in solution strongly depend on the chain length of the guest rather than its degree of unsaturation.
摘要
能够螯合二价阴离子的金属冠醚配合物，如在固态中所示，在中性pH值的水溶液中也存在，这已通过量热和质谱数据得到证明。溶液中这些二聚体配合物形成的驱动力很大程度上取决于客体的链长而非其不饱和度。
