12-Bromo-1,2,3,4-tetrahydro-1,4-ethano-anthracen-11-ol

Abstract

The title compound, C16H15BrO, 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-3 symmetry. There are two molecules in the asymmetric unit. Two strong hydrogen bonds, with D center dot center dot center dot A distances of 2.765(2) and 2.818(2) A , are observed between O atoms.
