12-Bromo-1,2,3,4-Tetrahydro-1,4-Ethano-Anthracen-11-ol

Abstract

The title compound, C<inf>16</inf>H<inf>15</inf>BrO, contains two non-planar six-membered rings constituting a bicyclic system. One of these rings shares two C atoms with an ethanoanthracene moiety, while the second ring has bromo and hydroxy substituents. The bicyclic system has approximate D <inf>3</inf> symmetry. There are two molecules in the asymmetric unit. Two strong hydrogen bonds, with D⋯A distances of 2.765 (2) and 2.818 (2) Å, are observed between O atoms. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
