Negatively charged ions with significantly different radii , e.g. Cl ⊖ , Br ⊖ and I ⊖ , can be encapsulated as guest molecules in VO‐cluster shells such as {V 18 O 42 } 1 . According to X‐ray structure analyses the encapsulated ions are fixed in the center of 1 and are surrounded by 18 V atoms and 24 O atoms. The distance from the center of the cluster to the O and V atoms of the periphery is on average 367.5 and 375.0 pm, resp. (V = black, O = white).
