In the title compound, C25H18O2S·C4H8O2, there are intermolecular O—H⋯O hydrogen bonds between the main molecule and the solvent molecule. The thiophene ring is oriented at dihedral angles of 70.87 (7) and 75.36 (4)° with respect to the mean planes of the two naphthyl ring systems.

Thiophene-2-carbaldehyde (1.68 g, 0.015 mol) and 1-p-tolylethanamine (2.025 g, 0.015 mol) was added to 2-naphthol (2.16 g, 0.015 mol) without solvent under nitrogen. The temperature was raised to 120°C in one hour gradually and the mixture was stirred at this temperature for 10 h. The system was treated with 20 ml of ethanol 95% and cooled. The precipitate was filtered and washed with a small amount of ethanol 95%. The title compound was isolated using
(petroleum ether:ethyl acetate 2:1). Single crystals suitable for X-ray were obtained from slow evaporation of ethyl acetate solution.H atoms were positioned geometrically and refined using a riding model, with C—H = 0.91–0.96 Å and Uiso(H) = 1.3–1.5Ueq(C).

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

The molten reaction of 2-naphthol, thiophene-2-carbaldehyde and 1-p-tolylethanamine at 120°C did not yield a Betti-type product, but the title bisnaphthol compound. Bisnaphthols are usually referred to as a diverse group of synthetic compounds containing two naphthol units which are connected by an aldehyde group. They have synthetic, medicinal and industrial value (Handique & Barauh et al. 2002). Here we report the synthesis and crystal structure of the title compound. The asymmetric unit of the compound contains an ethyl acetate solvent molecule (Fig. 1). The bond lengths and angles are within normal ranges (Allen et al. 1987).
Rings of the two naphthols and thiophene are, of course, planar. The dihedral angles between rings A (C2–C6/C11) and B (C6–C11), and between rings C (C12–C16/C21) and D (C16–C21), are 0.87 (4) and 1.57 (3), respectively. The orientation of ring E (C22–C25/S1) with respect to the mean planes of the two naphthyl groups containing rings A and B, and C and D, may be described by the dihedral angles of 70.87 (7) and 75.36 (4), respectively. The dihedral angle between the mean planes of the two naphthyl groups is 75.36 (4).
As can be seen from the packing diagram (Fig. 2), intermolecular O—H···O hydrogen bonds (Table 1) link the molecules. Dipole–dipole and van der Waals interactions are also effective in the molecular packing.
