“…More than 4000 such compounds are separated and identified from plants [5]. Out of these, quercetin, morin, and rutin are best known and studied [6][7][8]. These compounds are potential antibacterial, anticancer, antiinflammatory, and anti-allergic agents and their intake is very important to prevent a number of diseases, which cause free-radical-mediated damage [4,9].…”

This study examines the interaction of Mg(II) and Ca(II) with morin (2 0 ,3,4 0 ,5,7-pentahydroxyflavone) in conjunction with the appraisal of antioxidant and biological properties of the complexes. The complexes were characterized by UV-Vis spectroscopy, FT-IR, 1 H NMR, 13 C NMR, thermal, and elemental analyses. The complexes have also been studied to determine metal : ligand stoichiometry. For antioxidant studies, it may be induced that complex formation increases the scavenging ability because of the differential and selective role of metals in free radical scavenging. The bioactivity studies show that both complexes have remarkable antibacterial properties against Micrococcus flavus and Staphylococcus aureus.

“…Furthermore, chrysin has demonstrated anti-cancer activities [6,7]. Chrysin and its sulfonate derivatives are able to coordinate metal ions [8][9][10][11][12]. In this article, we report a copper(II) complex of a chrysin sulfonate, Cu(C 15 H 8 O 7 S)(3H 2 O).…”

A copper(II) complex of a sulfonate derivative of chrysin, 5,7-bihydroxyflavone-6-sulfonate, Cu(C 15 H 8 O 7 S)(3H 2 O), has been prepared. The complex was characterized by elemental analysis, spectroscopic measurements and single-crystal X-ray diffraction studies. It crystallizes in the monoclinic space group C2/c, with a ¼ 16.036 (18)In the complex, Cu(II) is five-coordinate and all donors are oxygen atoms. Hydrogen bonds and -stacking interactions in the crystal lead to the formation of a three-dimensional supramolecular motif.

“…It has poor solubility in water and fat (Suo et al, 2005). One effective way to increase the solubility of these compounds is to involve a sulfonate group, see: Kopacz (1981); Pusz et al (2001); Xie et al (2002). 8.1977 (3) Å c = 14.3431 (7) Å = 73.626 (3) = 80.346 3= 65.498 (3) V = 810.61 (6) Å 3 Z = 2 Mo K radiation = 0.26 mm À1 T = 296 K 0.20 Â 0.20 Â 0.05 mm…”

In the title compound [systematic name: 5-(5,7-dihydroxy-4-oxo-4H-chromenyl)-2-hydroxybenzenesulfonic acid dihydrate], C15H10O8S·2H2O, the benzopyranone ring is not coplanar with the phenyl ring, the dihedral angle between them being 41.35 (3)°. No H atom was placed on the sulphonic acid group because it was not possible to distinguish between the two S=O bonds and the S—O bond. In the crystal, the molecules are linked by classical O—H⋯O and C—H⋯O intra- and intermolecular hydrogen bonds and aromatic π–π stacking interactions [centroid–centroid distance of 3.4523 (14) Å between the 1, 4-pyranone rings and the benzene rings, and 3.6337 (14) Å between the benzene rings] into a supramolecular structure.
