Intercalation Host The cover image depicts the analysis of the metastability of a novel iridium‐doped VO 2 phase. The background shows an intensity map of powder X‐ray diffraction patterns acquired upon heating and cooling. The diffraction patterns illustrate the transition from the novel metastable tunnel structure to the thermodynamically stable R state and subsequently to the low‐temperature M 1 phase. The data represents the finding that alloying with iridium stabilizes a new metastable tunnel‐structured phase of VO 2 and that this phase is stable up to ca. 350 °C. The metastable structure is found to form as nanoplatelets, and owing to its tunnel structure and the availability of redox states in vanadium, has potential to serve as a host for ion intercalation.
