CRYSTAL AND MOLECULAR STRUCTURE OF BENZO-13-CROWN-4

<正> To elucidate structural relations between benzo-13-crown-4 and its similar crown compound. We determined the crystal structure of the title compound, which is a pure crown. The results of our investigation show that the dihedral angle between the planes of benzo-ring and of the O-atoms in the crown ring is 43.5°. The related distances between O atoms in benzo-13-crown-4 are 2.651 to 4.906, respectively.
