Bi(III) ions are capable of reversible, multicomponent self assembly with suitable tris-coordinate ligands. The nature of the self-assembled structures observed are dependent on the ligand coordination geometry, ligand protonation state and Bi concentration. These assemblies can exploit the maximum number of coordination sites at the Bi vertices (nine), and the self-assembly process has been studied by 1D NMR, Diffusion NMR, ESI-MS and X-ray crystallographic analysis. V-shaped coordinating ligands reversibly form discrete M2L4, M2L3, and M2L2 complexes dependent on ligand/bismuth concentration, whereas a linear coordinating ligand forms a single discrete M3L3 assembly.
Bi(III) 离子能够与合适的三配位体进行可逆的多组分自组装。所观察到的自组装结构的性质取决于配体的配位几何形状、配体的质子化状态和 Bi 的浓度。这些组装体可以利用 Bi 顶点的最大配位位点数(九个),并通过一维核磁共振、扩散核磁共振、ESI-MS 和 X 射线晶体学分析对自组装过程进行了研究。V 形配位配体可逆地形成离散的 M2L4、M2L3 和 M2L2 复合物,这取决于配体/铋的浓度,而线性配位配体则形成单一的离散 M3L3 组装。
