| Abstract: | The macrocyclic complex Ni2(L)(OAc)]ClO4 ( 1 ) adsorbs up to 17 molar equivalents (>270 wt %) of iodine, although it does not exhibit permanent porosity. Vibrational spectroscopic and crystallographic studies reveal that two I2 molecules are captured by means of thiophenolate→I2 charge‐transfer interactions, which enable the diffusion and sorption of further I2 molecules in a polyiodide‐like network. The efficient sorption and desorption characteristics make this material suitable for accommodation, sensing, and slow release of I2. |
