Crystal structure and Hirshfeld surface analysis of (2,7-diethoxynaphthalene-1,8-diyl)bis[(4-bromophenyl)methanone]
The title compound, C<sub>28</sub>H<sub>22</sub>Br<sub>2</sub>O<sub>4</sub>, crystallizes in the monoclinic space group <i>P</i>2<sub>1</sub>/<i>c</i> at 193 K. The two 4-bromo-benzoyl groups are attached in a non-coplanar fashion to the naphthalene ring system and are oriented in opposite directions. The two 4-bromo-benzene rings are tilted almost symmetrically with respect to the naphthalene ring system. The crystal packing features several kinds of non-classical hydrogen bonds such as C-H⋯<i>X</i> (<i>X</i> = polar atom), in which the C-H group acts as a hydrogen-atom donor, and C-H⋯π inter-actions. The two-dimensional fingerprint plots generated in a Hirshfeld surface analysis show non-classical hydrogen bonding with short contacts involving the bromo group.
