Abstract
Solid-state structures are determined for two compounds which contain dibenzo-13-crown-4 rings. These include the parent crown ether dibenzo -13-crown-4 and its lariat ether derivative sym-(2-picolyloxy)dibenzo- 13-crown-4. The solid-state structure of dibenzo-13-crown-4 is complic ated by disorder of the carbon atoms in the ethylene and propylene bri dges. The asymmetric unit of the crystal for the lariat ether derivati ve consists of two chemically identical, but crystallographically diff erent, molecules.
