Abstract

In the self-assembly of M_nL_2n 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 finely resolved 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 switch was fully confirmed by X-ray crystallography, mass spectrometry, NMR spectroscopy, and ultracentrifugation analyses.
