Trapping a Metastable Node in an Amorphous Metal–Organic Framework
Angewandte Chemie, EarlyView.Frustrated assembly in an amorphous Fe‐BDC framework is shown to trap a distorted, metastable Fe3O node as the dominant local motif. X‐ray PDF analysis and DFT calculations reveal that rapid network percolation outpaces node relaxation, locking in a high‐energy puckered geometry.
