In the title compound, C—H⋯O hydrogen bonds generate infinite (101) sheets.

Keywords: crystal structure, Hirshfeld surface analysis, coumarin

Abstract

In the title compound, C₁₈H₁₄O₄, the benzoate ring is oriented at a dihedral angle of 39.78 (5)° with respect to the coumarin ring system. In the crystal, the molecules are linked by C—H⋯O hydrogen bonds to generate infinite (101) layers.

Structure description

The title compound, C₁₈H₁₄O₄ (I), crystallizes in the monoclinic space group P2₁/c with one molecule in the asymmetric unit (Fig. 1 ▸). The side chain is titled with respect to the chromen-2-one ring system with torsion angles C18—C10—O2—C9 = −51.22 (16)° and C11—C10—O2—C9 = 133.18 (11)°. The C10–C18/O3 coumarin ring system is almost planar (r.m.s deviation = 0.012 Å) and makes a dihedral angle with the pendant benzoate ring system of 39.78 (5)°. The C14—C15 [1.342 (2) Å] and C15—C16 [1.447 (2) Å] bond lengths are consistent with the double and single bonds in the Lewis structure of (I) and with those in similar coumarin derivatives (Gomes et al., 2016 ▸; Ouédraogo et al., 2018 ▸).

The molecular structure of (I) with displacement ellipsoids drawn at the 50% probability level.

In the extended structure of (I), the molecules are connected by C—H⋯O hydrogen bonds (Table 1 ▸): the C11—H11⋯O1 and C12—H12⋯O3 bonds lead to [010] chains, which are cross-linked by the C15—H15⋯O4 bonds to generate (101) layers incorporating Inline graphic (11) and (13) loops (Fig. 2 ▸). The intermolecular interactions in (I) were further quantified by Hirshfeld surface (Fig. 3 ▸) analysis using CrystalExplorer (Spackman et al., 2021 ▸): the two-dimensional fingerprint plots for (I) (Fig. 4 ▸) show that the greatest contributions are from H⋯H (40.5%), H⋯O/O⋯H (26.1%) C⋯H/H⋯C (18.4%) and C⋯C (9.0%) contacts.

Synthesis and crystallization

In a 100 ml round-bottom flask equipped with a condenser, 4-ethylbenzoyl chloride (0.95 ml, 6.2 mmol, ∼1 equiv.) was dissolved in 30 ml of tetrahydrofuran and then were added dried triethylamine (2.6 ml, 3 equiv.) and 7-hydroxycoumarin (1 g, 6.17 mmol, 1 equiv.) in small portions over 30 min. While stirring, the mixture was refluxed for 4 h and poured into 40 ml of chloroform. The solution was acidified with dilute hydrochloric acid until its discoloration was complete. The organic phase was extracted, concentrated in a vacuum until a slight cloudiness was obtained and cooled in an ice bath. The resulting precipitate was filtered off with suction, washed with petroleum ether and recrystallized from a chloroform/n-hexane (1:3) solvent mixture resulting in a white powder of the title compound (1.15 g, 70% yield, m.p. = 407–409 K). Colorless crystals of (I) suitable for single-crystal X-ray diffraction analysis were then obtained by slow evaporation of an acetone solution.

2-Oxo-2H-chromen-7-yl 4-ethylbenzoate . Special details

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. The H atoms were located in difference maps and their positions and U_iso values were freely refined.
