dc.description.abstract© 2015 by the authors; licensee MDPI.A new trinuclear oxo-centered chromium(III) complex with formula [Cr<inf>3</inf>O(CH<inf>3</inf>CO<inf>2</inf>)<inf>6</inf>(L)(H<inf>2</inf>O)<inf>2</inf>] (L = 5-hydroxyflavone, known as primuletin) was synthetized and characterized by ESI mass spectrometry, thermogravimetry, and <sup>1</sup>H-NMR, UV-Vis, and FTIR spectroscopies. In agreement with the experimental results, DFT calculations indicated that the flavonoid ligand is coordinated to one of the three Cr(III) centers in an O,O-bidentate mode through the 5-hydroxy/4-keto groups. In a comparative study involving the uncoordinated primuletin and its corresponding complex, systematic reactions with the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) showed that antiradical activity increases upon complexation.
