Crystal structure and Hirshfeld surface analysis of (2,7-di-eth-oxy-naphthalene-1,8-di-yl)bis-[(4-bromophen-yl)methanone].

ABSTRACT: The title compound, C₂₈H₂₂Br₂O₄, crystallizes in the monoclinic space group P2₁/c 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⋯X (X = 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.
