Crystal structure of the complex of brominated diphenyl ethers from the marine spongeDysidea fragilis

Abstract

The spatial structures of 2-(2′,4′-dibromophenoxy)-3,4,5-tribromophenoI (1) and 2-(2′-hydroxy-4′,6′-dibromophenoxy)-4,6-dibromoanisole (2) in crystals of the complex formed through two intermolecular O-H-O bonds were determined. The conformations of both molecules were found to be stabilized by intermolecular hydrogen bonds. The external hydrophobic surface of the complex of two molecules was shown to be occupied by nine bromine atoms.
