Tris(3,7-dihydroxyflavonolate-κO3,O4)chromium(III) Complex

The complex [Cr(3,7diHF)3]·3H2O (3,7diHF is the monoanion of flavonoid 3,7-dihydroxyflavone) was synthetized and characterized by mass spectrometry, thermogravimetry, UV-Vis and FTIR spectroscopies. The data indicated that the coordination of the chromium(III) ion to the flavonoid increased its thermal stability.
