(18-Crown-6)potassium chlorochromate
Abstract
The crystal structure of the title compound, (1,4,7,10,13,16-hexaoxacyclooctadecane-6O)potassium chlorochromate(VI), K(C12H24O6)CrClO3, contains a K+ cation, complexed with one crown ether molecule, and a chlorochromate anion. The cation is located within the mean plane of the ether O atoms, approximately in the centre of the macrocyclic cavity, and bonded to them with K-O distances in the range 2.785 (5)-2.836 (5) A. In the crystal structure, polymeric chains of the type K+-CrO-K+ are formed.
