In the title compound, C22H27BrO3, the cyclohexane ring adopts a chair conformation. The dihedral angle between the benzene rings is 41.9 (4)°. In the crystal, molecules are linked by O—H⋯O and C—H⋯O hydrogen bonds, forming a three-dimensional network. In addition, π–π stacking interactions [centroid–centroid distance = 3.953 (6) Å] between the benzene rings of the methoxybenzene groups occur.

2-(1-(4-Bromophenyl)-3-hydroxy-3-(4-methoxyphenyl)propyl)cyclohexanol was synthesized from 2-(1-(4-bromophenyl)-3-(4-methoxyphenyl)-3-oxopropyl)cyclohexanone (1,5-diketone) (Ceylan & Gezegen, 2008; Gezegen et al., 2010). To a solution of 2-(1-(4-bromophenyl)-3-(4-methoxyphenyl)-3-oxopropyl)cyclohexanone (1 mmol) in THF-MeOH (12 ml 5:1) was added NaBH4 (3 mmol) and stirred for 16 h at room temperature. After completion of the reaction, the mixture was transferred to a separatory funnel, dilute HCl (10% 10 ml) was added and extracted with diethyl ether (3x20 ml). The organic layer was dried over Na2SO4 and evaporated. The crude product was crystallized from EtO2-hexane (3:1) to give pure 2-(1-(4-bromophenyl)-3-hydroxy-3-(4-methoxyphenyl)propyl)cyclohexanol in 75% yield; m.p.: 470–472 K.
C-bound H atoms and the hydroxyl H atom H1A were positioned geometrically and refined using a riding model with O—H = 0.82 Å, C—H = 0.93 Å (aromatic), 0.96 Å (methyl), 0.97 Å (methylene) and 0.98 Å (methine), and with Uiso(H) = 1.5Ueq(Cmethyl, Ohydroxyl), and Uiso(H) = 1.2Ueq(Caromatic, methylene, methine). The other hydroxyl H atom H2A was found in difference Fourier maps and the O2—H2A bond length were restrained to 0.83 (2) Å with Uiso(H) = 1.5Ueq(O). Twelve poorly fitted reflections (2 2 1), (0 2 2), (-25 3 19), (-9 3 7), (-10 2 20), (-13 7 5), (-6 2 6), (2 0 0), (-6 2 10), (10 6 2), (-9 11 3) and (-15 5 6) were omitted from the
owing to bad disagreement between Fo and Fc.1,5-Diols are useful and important compounds as intermediates in synthetic organic reactions (Huang et al., 2009; Oger et al., 2010). They are used in the synthesis of bioactive molecules and natural products (Flamme & Roush, 2005; Hansen et al., 2003). In this paper we report synthesis of 2-(1-(4-bromophenyl)-3-hydroxy-3-(4-methoxyphenyl)propyl)cyclohexanol in moderate yield together with its crystal structure.
The cyclohexyl ring of the title compound (I, Fig. 1) adopts a chair conformation with the puckering parameters (Cremer & Pople, 1975) of QT = 0.564 (6) Å, θ = 2.7 (6) ° and φ = 12 (13)°. The two benzene rings (C1–C6 and C16–C21) make a dihedral angle of 41.9 (4)° with each other. The C6–C7–C8–C13, C6–C7–C14–C15, C7–C14–C15–O2 and C7–C14–C15–C16 torsion angles are 177.9 (4), 59.2 (6), 64.0 (5) and -171.5 (4)°, respectively. All bond lengths of (I) are within normal ranges (Allen et al., 1987), as are the bond angles.
In the crystal, intermolecular O—H···O and C—H···O hydrogen bonds connect molecules, forming a three-dimensional network (Table 1, Fig. 2). Furthermore, π-π stacking interactions [Cg3···Cg3(2 - x, y, 1/2 - z) = 3.953 (6) Å, where Cg3 is a centroid of the C16–C21 benzene ring], between the benzene rings of the methoxybenzene groups, stabilize the crystal packing.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

1,5-Diols are useful and important compounds as intermediates in synthetic organic reactions (Huang et al., 2009; Oger et al., 2010). They are used in the synthesis of bioactive molecules and natural products (Flamme & Roush, 2005; Hansen et al., 2003). In this paper we report synthesis of 2-(1-(4-bromophenyl)-3-hydroxy-3-(4-methoxyphenyl)propyl)cyclohexanol in moderate yield together with its crystal structure.
The cyclohexyl ring of the title compound (I, Fig. 1) adopts a chair conformation with the puckering parameters (Cremer & Pople, 1975) of QT = 0.564 (6) Å, θ = 2.7 (6) ° and φ = 12 (13)°. The two benzene rings (C1–C6 and C16–C21) make a dihedral angle of 41.9 (4)° with each other. The C6–C7–C8–C13, C6–C7–C14–C15, C7–C14–C15–O2 and C7–C14–C15–C16 torsion angles are 177.9 (4), 59.2 (6), 64.0 (5) and -171.5 (4)°, respectively. All bond lengths of (I) are within normal ranges (Allen et al., 1987), as are the bond angles.
In the crystal, intermolecular O—H···O and C—H···O hydrogen bonds connect molecules, forming a three-dimensional network (Table 1, Fig. 2). Furthermore, π-π stacking interactions [Cg3···Cg3(2 - x, y, 1/2 - z) = 3.953 (6) Å, where Cg3 is a centroid of the C16–C21 benzene ring], between the benzene rings of the methoxybenzene groups, stabilize the crystal packing.
