Crystal structures of ethyl 6-(4-methylphenyl)-4-oxo-4H-chromene-2-carboxylate and ethyl 6-(4-fluorophenyl)-4-oxo-4H-chromene-2-carboxylate
The crystal structures of two chromone derivatives are described, one of which has two independent molecules in the asymmetric unit. A comparison of the dihedral angles between the mean planes of the central chromone core with those of the substituents shows that each molecule differs significantl...
