The dihedral angle between the benzene rings is 39.03 (11) . The title molecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, molecules are linked into inversion dimers by pairs of inter-molecular C - H?O hydrogen bonds, generating R2 2(14) loops. Fun et al. 2011.Article
