Finely Resolved Threshold for the Sharp M<sub>12</sub>L<sub>24</sub>/M<sub>24</sub>L<sub>48</sub>Structural Switch in Multi-Component M<sub><i>n</i></sub>L<sub>2<i>n</i></sub>Polyhedral Assemblies: X-ray, MS, NMR, and Ultracentrifugation Analyses
the self‐assembly of MnL2n polyhedra, the bend angle (θ) of the divalent ligand components determines the final structure. The threshold for the sharp structural switch between M12L24 and M24L48 was finelyresolved to within just 4° by demonstrating the exclusive formation of M12L24 cuboctahedra or M24L48 rhombicuboctahedra from two similar ligands with θ values of 130° and 134°. This sharp structural
在M n L 2 n多面体的自组装中,二价配体组分的弯曲角(θ)确定了最终结构。M 12 L 24和M 24 L 48之间尖锐的结构转换阈值通过将两个相似的θ配体独家形成M 12 L 24八面体或M 24 L 48菱形八面体而精确地解析为仅4°值分别为130°和134°。这种尖锐的结构转换已通过X射线晶体学,质谱,NMR光谱和超速离心分析得到了充分证实。
