In the title compound, C18H11Br2ClO3, an intra­molecular O—H⋯O=C hydrogen bond occurs, forming a six-membered ring. The naphthalene ring system and the benzene ring make a dihedral angle of 57.36 (9)°. The central carbonyl C—(C=O)—C group is twisted away from the naphthalene ring system and the benzene ring by 18.61 (15) and 26.25 (16)°, respectively. In the crystal structure, two inter­molecular Br⋯Cl close contacts [3.4927 (7) and 3.4325 (7) Å] are observed.

Recently, we reported the crystal structures of 1-aroylated 2,7-dimethoxynaphthalenes, 1-(4-chlorobenzoyl)-2,7-dimethoxynaphthalene (Mitsui, Nakaema, Noguchi, Okamoto & Yonezawa, 2008), (4-chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone (Mitsui, Nakaema, Noguchi & Yonezawa, 2008), (4-chlorophenyl)(2-ethoxy-7-methoxynaphthalen-1-yl)methanone (Mitsui et al., 2009), 1-bromo-8-(4-chlorobenzoyl)-7-hydroxy-2-methoxynaphthalene (Mitsui, Nakaema, Nagasawa et al., 2010) and (8-bromo-2,7-dimethoxy-1-naphthyl)(4-chlorophenyl)methanone (Mitsui, Nagasawa, Watanabe et al., 2010). As a part of our ongoing studies on the synthesis and crystal structure analysis of aroylated naphthalene derivatives, we prepared and analysed the structure of crystal of 2,5-dibromo-4-(4-chlorobenzoyl)-3-hydroxy-6-methoxynaphthalene, (I). The title compound was prepared by electrophilic aromatic bromination reaction of (4-chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone with bromine.

An ORTEPIII (Burnett & Johnson, 1996) plot of (I) is shown in Fig. 1. In the molecule of (I), the intramolecular O—H···OC hydrogen bond, which forms a six-membered ring including the CO group and an edge of the naphthalene ring, is present (Table 1). The conformation of these groups resembles to that of (4-chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone (Mitsui, Nakaema, Noguchi & Yonezawa, 2008). Intriguingly, the central CO group is twisted away from the naphthalene ring and the benzene ring, and the bromo group at 8-position of naphthalene is out of the least-squares plane of the naphthalene ring. The angles of the CO bond vector against the least-squares plane of the naphthalene ring and the benzene ring are 18.61 (15) and 26.25 (16)°, respectively. The angle of the C9—Br1 bond vector against the least-squares plane of the naphthalene ring is 14.93 (7)°. This is presumably caused by release of the large steric repulsion brought about by the benzene ring and the bromo group on the naphthalene ring of (I).

In the crystal structure, the contact distances Br1···Cl1 and Br2···Cl1 are 3.4927 (7) and 3.4325 (7) Å, respectively (Fig. 2). These contacts are shorter than the sum of their van der Waals radii (3.60 Å), and the five atoms are arranged nearly linear [C9—Br1···Cl1 = 154.14 (6)°, C3—Br2···Cl1 = 165.35 (7)°], suggesting that there is a possibility for halogen interaction (Saruma & Desiraju, 1986; Pedireddi et al., 1994; Moorthy et al., 2002).

Experimental top

To a solution of (4-chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone (313 mg, 1.00 mmol) in chloroform (5 ml) was added Br2 (483 mg, 3.03 mmol) drop-wise. The reaction mixture was heated at reflux for 2 h, then poured into aqueous 2 M Na2S2O3 (10 ml), and the aqueous layer was extracted with CHCl3 (3 × 10 ml). The combined organic layers were washed with 2 M Na2S2O3 (3 × 30 ml) and brine (3 × 30 ml), and dried over MgSO4 overnight. The solvent was removed in vacuo and the crude material was purified by column chromatography (silica gel, CHCl3) to give the title compound (yield 306 mg, 65%). Single crystals suitable for X-ray diffraction analysis were obtained from CHCl3 as yellow blocks (m.p. 455.0–455.5 K).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

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.
