Abstract: The title compound, (cis-syn-cis-icosahydrodibenzo[b,k][1,4,7,10,13,16]hexaoxacyclooctadecin)potassium chlorochromate, [K(C₂₀H₃₆O₆)][CrClO₃], is the complex of a potassium cation with one crown ether molecule and a chlorochromate anion. The cation is situated in the macrocyclic cavity and bonded to the ether O atoms with K-O distances in the range 2.749 (4)-2.991 (3) Å. It also forms two bonds with O atoms of the anion [2.789 (5) and 3.315 (7) Å].
