Head-to-tail square-shaped cyclic hydrogen bonds leading to dimeric aggregates: 1,8-dibenzoyl-2,7-di­hydroxy­naphthalene and a comparison with its analogous benzoyl­naphthalene

S. Mohri, S. Yoshiwaka, K. Isozaki, N. Yonezawa and A. Okamoto

Synopsis: In 1,8-dibenzoyl-2,7-di­hydroxy­naphthalene, centrosymmetric dimeric aggregates arise from two intra- and inter­molecular O-H...O=C hydrogen bonds, forming head-to-tail square-shaped cyclic ...O...H...O...H... hydrogen bonds. These dimeric aggregates are connected into layers in the bc plane by inter­molecular (naphthalene)C-H...O=C inter­actions.

Formula: C24H16O4
