The title compound, C24H16O4, crystallized with two independent mol­ecules in the asymmetric unit. Both carbonyl groups in these mol­ecules form intra­molecular O—H...O=C hydrogen bonds with neighbouring hy­droxy groups, affording six-membered cyclic structures. In the crystal, dimeric aggre­gates arise from two intermolecular O—H...O=C hydrogen bonds between both independent molecules, 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. On the other hand, the analogous compound bearing meth­oxy groups at the 2- and 7-positions of the naph­thal­ene ring, namely 1,8-dibenzoyl-2,7-di­meth­oxy­naph­tha­lene [Nakaema et al. (2008). Acta Cryst. E64, o807], forms a three-dimensional mol­ecular network via C—H...O=C and π–π inter­actions between the benzoyl groups. These results show that the intramolecular O—H...O=C hydrogen bonds in the title compound control the orientations of the benzoyl groups and thus promote the formation of the cyclic intermolecular O—H...O=C interactions involving the same donor and acceptor groups in pairs of molecules.

Introduction top

Molecules with noncoplanar aromatic rings, e.g. bi­naphthyl and bi­phenyl compounds, have been in the limelight because of their unique spatial shapes causing characteristic properties and various applications (Alfonso et al., 200; Gasparrini et al., 2008; Zhang et al., 2011). Peri-substituted naphthalenes have also received much attention as characteristic structured aromatic core compounds for a variety of functional materials (Mei et al., 2006; Shinamura et al., 2010; Jiang et al., 2010). Therefore, the structural analyses have been actively performed (Gore et al., 1980; Cohen et al., 2004; Jing et al., 2005). Recently, the authors group has revealed that diaroylation at 1,8-positions of naphthalene proceeds smoothly (Okamoto & Yonezawa, 2009; Okamoto et al., 2011).

According to X-ray crystal studies, the resulting 1,8-diaroylated naphthalene derivatives, such as 1,8-di­benzoyl-2,7-di­meth­oxy­naphthalene (Nakaema et al., 2008), have a noncoplanar organization of the aromatic rings. Herein, the X-ray crystal structure of the title compound, 1,8-di­benzoyl-2,7-di­hydroxy­naphthalene, (I), is reported. The compound has two hy­droxy groups at the 2- and 7-positions of the naphthalene ring in place of the alk­oxy groups of the above-mentioned compound. We report the single-crystal structure and the molecular packing of (I) and discuss the structure-determining factors through comparison with the analogous molecule.

Synthesis and crystallization top

To the solution of 1,8-di­benzoyl-2,7-di­eth­oxy­naphthalene (5.0 mmol, 2.1 g) and toluene (25 ml), AlCl3 (25.0 mmol, 3.3 g) was added and stirred at 363 K for 1 h. The reaction mixture was poured into 2 M aqueous HCl, and it was extracted with CHCl3. The combined extracts were washed with brine and dried over anhydrous MgSO4. The solvent was removed under reduced pressure to give cake. The crude product was purified by recrystallization from toluene (48% isolated yield; m.p. 501.4–502.1 K). 1H NMR (300 MHz, CDCl3): δ 7.13 (2H, d, J = 8.9 Hz), 7.19 [4H, d (broad), J = 7.6 Hz], 7.30 (4H t, J = 7.6 Hz), 7.50 (2H, t, J = 7.6 Hz), 7.92 (2H, d, J = 8.9 Hz), 11.24 (2H, s). 13C NMR δ (75 MHz, CDCl3): 115.39, 117.13, 122.16, 128.17, 131.61, 132.82, 133.00, 136.38, 136.49, 161.99, 197.26. IR (KBr, cm-1): 3441 (O—H), 1661 (C O), 1595, 1513, 1451 (Ar, naphthalene). Elemental analysis calculated for C24H16O4: C 78.25, H 4.38%; found: C 78.10, H 4.41%.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 1. All H atoms could be located in difference Fourier maps, but were subsequently refined as riding atoms, with O—H = 0.84 Å and Uiso(H) = 1.5Ueq(O) for hy­droxy H atoms, and C—H = 0.95 Å and Uiso(H) = 1.2Ueq(C) for aromatic H atoms.

Results and discussion top

There are two independent molecules (A and B) in the crystal of (I) with display intra­molecular O—H···OC hydrogen bonds between the hy­droxy and carbonyl groups (Fig. 1). Each independent molecule has essentially the same noncoplanar organization of aromatic rings, as indicated by a least-squares fit of the two molecules (r.m.s. deviation = 0.003 Å). The dihedral angles between the benzene rings are 9.10 (11) (for molecule A) and 2.37 (10)° (for molecule B), and those between the benzene rings and the naphthalene system are 62.77 (10) and 56.43 (8)° (for molecule A), and 54.68 (8) and 54.74 (9)° (for molecule B).

In the crystal packing, centrosymmetrically related molecules are connected into a supra­molecular dimer via head-to-tail square-shaped cyclic hydrogen bonds involving two intra- and inter­molecular CO···H hydrogen bonds between the hy­droxy H atoms and the carbonyl O atoms (Table 2 and Fig. 2). The dimeric aggregates are arranged in layers in the bc plane by C—H···OC hydrogen bonds between the naphthalene rings and the carbonyl groups unrelated with the formation of the square-shaped cyclic hydrogen bonds (C3—H3···O6; Table 2 and Fig. 2). Inter­molecular C—H···O inter­actions between the benzene rings of the benzoyl groups and the hy­droxy groups (C21—H21···O4iii; Table 2 and Fig. 2) contribute to the stability of the molecular alignments along the b axis.

Several years ago, the authors published the crystal structure of a 1,8-di­benzoyl­naphthalene analogue bearing meth­oxy groups at the 2- and 7-positions, namely 1,8-di­benzoyl-2,7-di­meth­oxy­naphthalene, (II) (Nakaema et al., 2008; Fig. 3). The molecules are located on a twofold rotation axis. The molecular packing strikingly differs from that of (I). In the crystal of (II), a three-dimensional molecular network is formed by benzene and methyl C—H···OC inter­actions and benzene–benzene ππ stacking inter­actions (Fig. 4). The dihedral angle between the benzene ring and the naphthalene system in (II) is larger than that of (I) [80.25 (6)° for (II), 62.77 (10) and 56.43 (8)° for molecule A of (I), and 54.68 (8) and 54.74 (9)° for molecule B of (I)].

The data indicate that intra­molecular O—H···OC hydrogen bonds fix the benzoyl groups in (I). Intra­molecular O—H···OC hydrogen bonds might play a key role in the smooth formation of a centrosymmetric dimer via head-to-tail square-shaped cyclic hydrogen bonds between the carbonyl and hy­droxy groups. In other words, the formation of the three-dimensional molecular network requires that benzoyl groups free of strong fixation can change appropriately the situation to make inter­molecular inter­actions, such as C—H···O and ππ.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
