Crystal structure of 2-(4-chlorophenyl)-3-hydroxy-4H-chromen-4-one.
Flavones are a subclass of flavonoids, secondary metabolites of plants which contain the 2-phenylbenzopyran pharmacophore. They are of interest as they display a wide variety of biological activities, such as anticancer and antioxidant. Recently, there has been an interest in coordinating flavones to various transition metals for anticancer activity. Our work in this area led to the synthesis and crystallization of flavones as intermediates. We reported the first crystal structure of 2-(4-chlorophenyl)-3-hydroxy-4H-chromen-4-one, C15H9ClO3, a well studied compound in IUCrData. https://doi.org/10.1107/S2414314617009968
