The title compounds, C23H16S, (I), and C26H16S, (II), are benzothiophene derivatives in which the benzothiophene moiety is fused with a naphthalene ring system in (I), and with an anthracene ring system in (II). In (I), the mean plane of the benzothiophene ring system makes a dihedral angle of 2.28 (6)° with the naphthalene ring system, and a dihedral angle of 1.28 (6)° with the anthracene ring system in (II), showing that the fused units are essentially planar. In (I), the 4-methylbenzene ring substituent makes a dihedral angle of 71.40 (9)° with the naphthalene ring system, while the phenyl ring substituent in (II) makes a dihedral angle of 67.08 (12)° with the anthracene ring system. In the crystals of both compounds, molecules are linked by C—H⋯π interactions, leading to the formation of slabs parallel to (001) in (I) and to zigzag chains along [001] in (II). There are also offset π–π interactions present within the slabs in (I). In the crystal of (II), they link the chains, forming sheets parallel to (010). The triclinic polymorph of compound (II) has been reported [Sivasakthikumaran et al., (2012). J. Org. Chem. 77, 9053–9071].
1. Chemical context
The thiophene nucleus has been shown to be an important heterocyclic unit in compounds possessing promising pharmacological characteristics, such as anti-HIV PR inhibitors (Bonini et al., 2005) and anti-breast cancer (Brault et al., 2005) activities. Benzothiophenes are important biologically active molecules. One of the most important drugs based on the benzothiophene system is Raloxifine, used for the prevention and treatment of osteoporosis in postmenopausal women (Jordan, 2003). Benzothiophenes are also present in luminescent components used in organic materials (Russell & Press, 1996).
Naphtho[2,3-b]thiophene derivatives have been found to exhibit antiproliferative activity related to the inhibition of tublin polymerization (Zuse et al., 2007, 2006). As a result of their outstanding electronic testability and considerable chemical and environmental stability, thiophene derivatives have been widely used in solar cells (Justin Thomas et al., 2008; Hänsel et al., 2003), organic light-emitting diodes (OLEDs) (Mazzeo et al., 2003), organic field-effect transistors (OFETs) (Zhan et al., 2007) and as NLO devices (Bedworth et al., 1996; Raposo et al., 2011).Against this background, we describe herein the syntheses and crystal structures of the title benzothiophene derivatives.
2. Structural commentary
The molecular structures of the title compounds, (I) and (II), are illustrated in Figs. 1 and 2, respectively. In both compounds, the benzothiophene ring systems are almost planar with the dihedral angles between the benzene and thiophene rings being 1.85 (11)° in (I) and 0.56 (18)° in (II).
In compound (I), the naphthalene ring system (atoms C1–C3/C10–C16) (r.m.s. deviation = 0.006 Å) makes a a dihedral angle of 2.28 (6)° with the benzothiophene (C3–C10/S1) ring system (r.m.s. deviation = 0.023 Å). The 4-methylbenzene ring substituent (C17–C22) makes a dihedral angle of 71.40 (9)° with the naphthalene ring system
In compound (II), the anthracene ring system (C1–C3/C10–C20) is almost planar (r.m.s. deviation = 0.075 Å) and makes a a dihedral angle of 7.31 (9)° with the benzothiophene (C3–C10/S1) ring system (r.m.s. deviation = 0.012 Å). Here, the phenyl ring substituent (C21–C26) in (II) makes a dihedral angle of 67.08 (12)° with the anthracene ring system, and the anthracene ring is (−)antiperiplanar with respect to the benzothiophene moiety, as indicated by the S1—C3—C10—C11 torsion angle of −176.4 (2)°.
In the triclinic polymorph of compound (II) (Sivasakthikumaran et al., 2012), the major component of the disordered phenyl ring substituent makes a dihedral angle of 79.39 (12)° with the anthracene ring system.
3. Supramolecular features
In the crystals of both compounds, molecules are linked by C—H⋯π interactions (see Tables 1 and 2), leading to the formation of slabs parallel to (001) in (I), and to zigzag chains along [001] in (II); as illustrated in Figs. 3, 4 and 5. There are also offset π–π interactions present within the slabs in (I) [Cg1⋯Cg3i = 3.629 (1) Å, interplanar distance = 3.602 (1) Å, slippage = 0.49 Å; Cg2⋯Cg4ii = 3.983 (1), interplanar distance = 3.473 (1), slippage 1.79 Å; Cg1, Cg2, Cg3 and Cg4 are the centroids of rings S1/C3/C4/C9/C10, C1–C3/C10–C12, C1/C12–C16 and C4–C9, respectively; symmetry codes: (i) x + 1, y, z; (ii) x − 1, y, z]. In the crystal of (II), offset π–π interactions link the chains, forming sheets parallel to (010) [Cg2⋯Cg4iii = 3.711 (2) Å, interplanar distance = 3.479 (1) Å, slippage = 1.21 Å; Cg3⋯Cg4iii = 3.741 (2) Å, interplanar distance = 3.443 (1) Å, slippage = 1.22 Å; Cg2, Cg3 and Cg4 are the centroids of rings C1–C3/C10–C12, C1/C12–C16 and C4–C9, respectively; symmetry code: (iii) −x + 1, −y + 1, −z + 1].
4. Database survey
A search of the Cambridge Structural Database (Version 5.38, update May 2016; Groom et al., 2016) for the naphthobenzothiophene skeleton gave 32 hits. Among these there are five naphthobenzothiophene derivatives that resemble compound (I), viz. 6-(phenyl)benzo[b]naphtho[2,3-d]thiophene (NEQMAZ; Silambarasan et al., 2013), 6-(4-methoxyphenyl)benzo[b]naphtho[2,3-d]thiophene (PECQEV; Silambarasan et al., 2012), 6-(2-thienyl)benzo[b]naphtho[2,3-d]thiophene (XIMZUQ; Sivasakthikumaran et al., 2012), 6-(1-benzothiophen-3-yl)benzo[b]naphtho[2,3-d]thiophene (HIXQUB; Li et al., 2007) and 1,3-dimethylbenzo[b]naphtho[2,3-d]thiophene (ROMPUF/ROMPUF01; Umarani et al., 2009/Dhayalan et al., 2009). There are also two anthracene analogues, viz. anthra[2,3-b]benzo[d]thiophene itself (JOHSOP; Du et al., 2008), and 7-(1-benzothiophen-2-yl)anthra[2,3-b]benzo[d]thiophene (FOLGEU; Rafiq et al., 2014); as well as the triclinic polymorph of compound (II) (XIMZOK; Sivasakthikumaran et al., 2012).
5. Synthesis and crystallization
Compound (I)
The reduction of the diketone (benzothiophen-3-yl)[2-(4-methylbenzoyl)phenyl]methanone (0.85 g, 2.38 mmol) using sodium borohydride (0.49 g, 12.89 mmol) followed by work-up gave the diol. Dipivaloylation of the diol (0.77 g, 2.31 mmol) using pivaloyl chloride (1.39 g, 11.52 mmol) and triethylamine (4.69 g, 45.20 mmol) in the presence of a catalytic amount of DMAP (10 mg) in dry DCM (20 ml) led to the isolation of dipivalate (benzo[b]thiophen-3-yl){2-[pivaloyloxy(p-tolyl) methyl]phenyl}methyl pivalate as a viscous liquid. Dipivalate (benzo[b]thiophen-3-yl){2-[pivaloyloxy(p-toyl) methyl]phenyl}methyl pivalate (0.98 g, 1.96 mmol) upon interaction with ZnBr2 (0.02 g, 0.13 mmol) followed by removal of solvent and column chromatographic purification (silica gel; hexane–ethyl acetate, 99:1) gave 6-(p-tolyl)benzo[b]naphtho[2,3-d]thiophene as a pale-green solid (yield 0.53 g, 78%). Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of (I) in ethyl acetate at room temperature (m.p. 391–393 K).
Compound (II)
The reduction of the diketone (2-benzoylphenyl)(dibenzo[b,d]thiophen-2-yl)methanone (1.11 g, 2.38 mmol) using sodium borohydride (0.53 g, 13.94 mmol) followed by work-up gave the diol. Dipivaloylation of the diol (1.12 g, 2.82 mmol) using pivaloyl chloride (1.70 g, 14.14 mmol) and triethylamine (5.72 g, 56.56 mmol) in the presence of a catalytic amount of DMAP (10 mg) in dry DCM (20 ml) led to the isolation of dipivalate (dibenzo[b,d]thiophen-2-yl){2-[phenyl(pivaloyloxy)methyl]phenyl}methyl pivalate as a thick liquid. Dipivalate (dibenzo[b,d]thiophen-2-yl){2-[phenyl(pivaloyloxy)methyl]phenyl}methyl pivalate (1.28 g, 2.26 mmol) upon interaction with ZnBr2 (0.02 g, 0.13 mmol) followed by removal of solvent and column chromatographic purification (silica gel; hexane–ethyl acetate, 99:1) gave a new orthorhombic polymorph of 7-phenylanthra[2,3-b]benzo[d]thiophene (yield 0.83 g, 72%) as a yellow solid. Single crystals suitable for X-ray diffraction were prepared by slow evaporation of a solution of the compound (II) in ethyl acetate at room temperature (m.p. 463–465 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 > 2sigma(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. |

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 > 2sigma(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. |
