Reaction of alkali metal ozonides (KO 3 , RbO 3 and CsO 3 ) with [18]crown‐6 in liquid ammonia yields compounds of the composition M([18]crown‐6)O 3 · x NH 3 with M = K ( x = 2), Rb ( x = 1) and Cs ( x = 8). The large intermolecular distance between adjacent radical anions in these compounds leads to almost ideal paramagnetic behavior according to Curie's law. Discrepancies concerning the structure of the ozonide anions in the K and Cs compound compared to a former investigation on Rb([18]crown‐6)O 3 ·NH 3 have been resolved by means of DFT calculations and a single‐crystal structure redetermination.
