(Received 10 October 2008; accepted 13 November 2008; online 22 November 2008)

The title compound, C26H26N2O2S, was prepared by the reaction of thio­phene-2,5-dicarboxylic acid and 2-amino-4-tert-butyl­phenol. One of the tert-butyl groups is disordered over two conformations, with occupancies of 0.539 (1) and 0.461 (2). The two 1,3-benzoxazole rings are almost planar, with dihedral angles of 0.83 (18) and 1.64 (17)° between the five- and six-membered rings. The thio­phene ring makes dihedral angles of 21.54 (19) and 4.49 (18)° with the planes of the five-membered oxazole rings. The crystal packing is controlled by ππ stacking inter­actions involving the thio­phene and benzene rings, with a centroid–centroid distance of 3.748 (2) Å.

Comment top

Fluorescent whitening agents have received considerable attention in the literature. They are attractive from several points of view in application (Chen et al., 2008). As part of our search for new fluorescent whitening agent compounds we synthesized the title compound (I), and describe its structure here.

In (I) (Fig. 1), the C12—S1 bond length of 1.715 (3)Å is comparable with C—S bond [1.688 (2) Å] reported (Cowley et al., 2002). The two 1,3-benzoxazole rings (N1/O1/C5-C11) and (N2/O2/C16-C22) are almost planar, with dihedral angles of 0.83 (18)° and 1.64 (17)°, respectively, between the five- and six-membered rings. The thiophene ring (S1/C12-C15) makes dihedral angles of 21.54 (19)° and 4.49 (18)°, respectively, with the five membered rings (O1/N1/C7/C8/C11) and (O2/N2/C16-C18).

In the crystal structure, there is no classical hydrogen bonds. The crystal packing is controlled by π-π stacking interactions involving the thiophene (Cg1: S1/C12-C15) and benzene (Cg2i: C17-C22) [ (i) 2 - x, 1 - y, - z] rings, with a centroid-centroid distance of 3.748 (2)Å.

Experimental top

A mixture of the thiophene-2,5-dicarboxylic acid (0.05 mol), and 4-tert-butyl-2-aminophenol (0.1 mol) was stirred in refluxing toluene (20 mL) for 4 h to afford the title compound (0.086 mol, yield 86%). Single crystals suitable for X-ray measurements were obtained by recrystallization from ethanol at room temperature.

Refinement top

H atoms were fixed geometrically and allowed to ride on their attached atoms, with C—H distances = 0.93 and- 0.96 Å, and with Uiso=1.2 or 1.5Ueq.

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.
