In the cation of the title organic ion pair compound, C₂₃H₂₀ClN₂O₃⁺·CH₃O⁻, the cyclohexyl ring shows a half-boat conformation and the dihedral angles between two benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°. In the crystal, centrosymmetrically related cations are linked into a dimer by pairs of N—H⋯N hydrogen bonds, generating an R₂²(12) ring motif. The anion interacts with the dimer through an N—H⋯O hydrogen bond. π–π interactions between pyran rings of adjacent dimers, with a centroid–centroid distance of 3.861 (2) Å, are also observed.

Comment top

Chromenes and their benzo-derivatives are very important heterocyclic compounds, in particular due to their application in a variety of industrial, biological and chemical syntheses (Geen et al., 1996; Ercole et al., 2009; Takakazu et al., 2001). Herein, we report the synthesis and crystal structure of a new chromene derivative.

The molecular structure of the title compound is shown in Figure 1. In the cation of this novel organic ion pair compound, the cyclohexyl ring shows in a half-boat conformation. The dihedral angles between the C1–C6 and C16–C21 benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°, respectively. In the crystal structure (Fig. 2), centrosymmetrically related cations form a dimer by two intermolecular N—H···N hydrogen bonds (Table 1). Between neighbouring dimers, π–π interactions between pyran rings (centroid-centroid distance = 3.861 (2) Å) are observed. Furthermore, the organic cations and the methanolate anion are linked by intermolecular N—H···O hydrogen bonds.

Experimental top

The title compound were synthesized by the reaction of 4-chlorobenzaldehyde (10 mmol), malononitrile (10 mmol) and 5-(4-methoxyphenyl)-1,3-cyclo-hexane-dione (10 mmol) according to the similar synthesis route reported in the literature (Wen et al., 2006; Kidwai et al., 2005). Single crystals of the title compound suitable for X-ray analysis were obtained by slow evaporation of a methanol solution at room temperature for one week.

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.
