Redetermination of (E)-3-(anthracen-9-yl)-1-(2-hy-droxy-phen-yl)prop-2-en-1-one.

ABSTRACT: The redetermined structure of title chalcone derivative, C(23)H(16)O(2), corrects errors in the title, scheme and synthesis in the previous report of the same structure [Jasinski et al. (2011 ?). Acta Cryst. E67, o795]. There are two independent mol-ecules in the asymmetric unit with slight differences in bond lengths and angles. The dihedral angle between the benzene ring and the anthracene ring system is 73.30?(4)° in one mol-ecule and 73.18?(4)° in the other. Both mol-ecules feature an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules are arranged into sheets lying parallel to the ac plane and further stacked along the b axis by ?-? inter-actions with centroid-centroid distances in the range 3.6421?(6)-3.7607?(6)?Å. The crystal structure is further stabilized by C-H?? inter-actions. There are also C?O [3.2159?(15)?Å] short contacts.
