Abstract
AbstractThe ability to construct complex molecular architectures with precise control is critical for realizing molecule‐based materials and functions. Using the assembly of a 60‐metal complex of ErIIIwith histidine as an example, we demonstrate the rational assembly of otherwise synthetically elusive polynuclear lanthanide hydroxide clusters directed by the combined set of I−and CO32−as templates. We succeeded in the stepwise transformation starting fromEr12toEr60by way of two key intermediatesEr34andEr48. TheEr12,Er34, andEr48core motifs represent respectively 1/6, 1/2, and 3/4 of the complete sodalite cage ofEr60. This work, representing a rare example of rationally constructing high‐nuclearity lanthanide clusters guided by judiciously chosen templates, is expected to stimulate more future efforts for the controllable synthesis of complex molecular or supramolecular architectures with unprecedented structural sophistication and possibly useful properties.
