Crystal structure of N (1)-phenyl-N (4)-[(E)-(pyren-1-yl)methyl-idene]benzene-1,4-di-amine.

In the title compound, C29H20N2, the dihedral angles subtended by the central p-phenyl-enedi-amine ring with respect to the mean plane of the terminal pyrenyl ring system (r.m.s. deviation = 0.027 Å) and the terminal N-phenyl ring are 29.34 (4) and 43.43 (7)°, respectively. The conformation about the C=N bond is E. In the crystal, mol-ecules are linked by N-H⋯π and C-H⋯π inter-actions forming chains propagating along the [10-2] direction. These chains are linked via π-π inter-actions [inter-centroid distances are in the range 3.5569 (11)-3.708 (1) Å], forming slabs lying parallel to (30-4).

Chemical context

Schiff bases often exhibit various biological activities, and in many cases have been shown to have anti­bacterial, anti­cancer, anti-inflammatory and anti­toxic properties (Lozier et al., 1975 ▸). They are used as anion sensors (Dalapati et al., 2011 ▸), as non-linear optical compounds (Sun et al., 2012 ▸) and as versatile polynuclear ligands for multinuclear magnetic exchange clusters (Moroz et al., 2012 ▸). The pyrene unit is one of the most commonly used fluoro­phores due to its strong luminescence and chemical stability (Aoki et al., 1991 ▸; Nishizawa et al., 1999 ▸; van der Veen et al., 2000 ▸). Another inter­esting feature of the pyrene unit is the π–π inter­action between pyrene aromatic rings in the crystal packing, which can permit the formation of highly ordered mol­ecular aggregates in the solid state by architecturally controlled self-assembly (Desiraju et al., 1989 ▸; Munakata et al., 1994 ▸). Pyrene is a commonly used fluoro­phore due to its unusual fluorescent properties: intense fluorescence signals, vibronic band dependence with the media (Karpovich & Blanchard, 1995 ▸), and use in fluorescence sensors (Bell & Hext, 2004 ▸) and excimer formation (Lodeiro et al., 2006 ▸). As a result of these particular properties and because of its chemical stability, it is also employed as a probe for solid-state studies (Corma et al., 2002 ▸) and polymer association (Seixas de Melo et al., 2003 ▸). We report herein on the crystal structure of the title compound, synthesized by the condensation reaction of 1-pyrenecarboxaldehyde and N-phenyl-p-phenyl­enedi­amine.

Structural commentary

The mol­ecular structure of the title compound is illustrated in Fig. 1 ▸. The compound is non-planar, the dihedral angles between the central benzene ring (C7–C12) and the terminal phenyl ring (C1–C6) and the mean plane of the pyrenyl ring system (C14–C29; r.m.s. deviation = 0.027 Å) being 43.43 (9) and 29.33 (7)°, respectively. The conformation about the C13=N2 bond is E with a C10—N2—C13—C14 torsion angle of 178.13 (15)°.

Supra­molecular features

In the crystal, mol­ecules are connected via N—H⋯π and C—H⋯π inter­actions forming zigzag chains propagating along [10]; see Table 1 ▸ and Fig. 2 ▸. These chains are linked via π–π inter­actions involving inversion-related pyrenyl rings, forming two-dimensional networks lying parallel to (30); see Fig. 3 ▸. The inter-centroid distances are 3.7051 (11), 3.708 (1), 3.6905 (11) and 3.5569 (11) Å for π–π inter­actions involving Cg3⋯Cg5ii, Cg3⋯Cg6ii, Cg4⋯Cg6ii and Cg6⋯Cg6ii, respectively, where Cg3, Cg4, Cg5 and Cg6 are the centroids of the C14–C17/C28–C27, C17–C20/C28–C29, C20–C24/C29 and C24–C29 rings, respectively [symmetry code: (ii) = −x + 1, −y, −z]. Inter­action Cg6⋯Cg6ii is a slipped parallel π–π inter­action with an inter­planar distance of 3.3614 (7) Å and a slippage of 1.163 Å.

Database survey

A search of the Cambridge Structural Database (Version 5.36; last update November 2014; Groom & Allen, 2014 ▸) gave 20 hits for Schiff bases derived from pyrene-1-carbaldehyde. A search for Schiff base compounds involving N-phenyl-p-phenyl­enedi­amine gave three hits. Of these three compounds, N 1-phenyl-N 4-(quinolin-2-yl­methyl­ene)benzene-1,4-di­amine {synonym: N-phenyl-4-[(quinolin-2-yl­methyl­ene)amino]aniline; WOJJIQ; Faizi et al., 2014 ▸} is the most similar to the title compound. Here the dihedral angles between the central benzene ring and the terminal phenyl ring and the quinoline ring system (r.m.s. deviation = 0.027 Å) are 44.72 (7) and 9.02 (4)°, respectively. In the title compound, the dihedral angles between the central benzene ring and the terminal phenyl ring and the pyrenyl ring system (r.m.s. deviation = 0.027 Å) are 43.43 (9) and 29.33 (7)°, respectively.

Synthesis and crystallization

80 mg (0.435 mmol) of N-phenyl-p-phenyl­enedi­amine were dissolved in 10 ml of absolute ethanol. To this solution, 100 mg (0.435 mmol) of pyrene-1-carbaldehyde in 5 ml of absolute ethanol was added dropwise under stirring. The mixture was stirred for 10 min, two drops of glacial acetic acid were then added and the mixture was further refluxed for 2h. The resulting yellow precipitate was recovered by filtration, washed several times with small portions of ice-cold ethanol and then with diethyl ether to give 150 mg (87%) of the title compound. Yellow block-like crystals suitable for X-ray analysis were obtained within 3 days by slow evaporation of a solution in MeOH.

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.
