Negatively charged ions with significantly different radii, e.g. Cl⊖, Br⊖ and I⊖, can be encapsulated as guest molecules in VO-cluster shells such as {V18O42} 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).
