Source of material

The titled compound was prepared by mixing resorcinol (2.0 g) and methyl 3-fluorobenzoylacetate (3.5 g) and then added conc. H2SO4 (8 mL, 75%). The temperature of the stirred mixture was increased to 35 °C. After stirring for 5 h, the mixture was poured into crushed ice and neutralized with a NaOH solution. The mixture was filtered under vacuum and the residue was washed with water. The resulting product was purified by silica gel column chromatography with 70% ethylacetate in hexane as eluent and the product was obtained as a yellow solid (4.5 g, 97%) and then recrystallized from ethanol by slow evaporation to obtain light-yellow crystals. m.p.: 209–211 °C.

Experimental details

A Bruker Smart APEX2 diffractometer with Mo Kα radiation was used for crystal evaluation and data collection [1]. The structure was solved by the direct method using the SHELXS [2] program and refined. The visual crystal structure information was performed using Mercury [3] system software. All C—Haromatic and O—H bond distances were restrained to 0.95 Å, 0.98 Å and 0.99 Å with Uiso(Haromatic) = 1.2Ueq and Uiso(Hhydroxyl) = 1.5Ueq of parent atom, respectively. The meta-fluorophenyl unit appeared to be disordered over two positions and PART instructions were used to model the disorder. The major component had site occupancy factor of 0.816. A two-component, non-merohedral twin with refined volume ratio of 0.784(1):0.216(1) was determined. The twin law used was [−1 0 −1; 0 −1 0; 0 0 1].

Comment

Coumarins are natural compounds and the first coumarin was already isolated in 1820 and now more than 1300 coumarins have been identified from natural sources [5], [6]. The class of coumarin compounds is known to possess a variety of biological activities such as anti-inflammatory [7], anti-oxidant [8], [9], antibacterial [10], anticoagulant [8], anti-tumor [11], and anti-viral activities [12]. It is profound that the presence of a fluorine in an organic molecule may have effects on the biological activity of the compound [13], [14].

The crystal structure of the title compound consists of two symmetrically independent molecules and each molecule has a meta-fluorophenyl and coumarinyl unit, respectively. The dihedral angle between the two units was found to be 127.28(4)° and 129.7(1)°, respectively. All bond parameters are comparable to closely related compounds in literature [15], [16], [17], [18], [19], [20], [21]. Neighbouring molecules are joined together via classical intermolecular O—H⋯O hydrogen bonds between the hydroxyl and carbonyl groups. Linking the molecules in this manner results in the formation of a one dimensional structure, which propagates along the crystallographic b axis.
