摘要

在包括化学、物理和生物化学研究在内的多个研究领域中，溶解金属阳离子都是重要的基础单核物种。然而，控制它们的配位几何是一项重大挑战。在本研究中，我们成功合成了溶解 Ba2+ 配合物，并对其进行了结构表征。[Ba(CH3CN)8]2+的配位几何形状是热力学稳定的方形反棱柱，而[Ba{(CH3)2CO}8]2+的配位几何形状则是罕见的立方结构。

Solvated Ba2+ with square antiprismatic and cubic coordination geometries

Solvated metal cations represent fundamental and crucial mononuclear species in various research fields, including chemical, physical, and biochemical studies. However, controlling their coordination geometry poses a significant challenge. In this study, we successfully synthesized and structurally characterized solvated Ba2+ complexes. The coordination geometry of [Ba(CH3CN)8]2+ was a thermodynamically stable square antiprism, while that of [Ba{(CH3)2CO}8]2+ exhibited a rare cubic structure, demonstrating a unique approach to controlling coordination geometry solely by altering crystallization solvents.
