The structure and electrochemical properties of metal complexes with dihydroquercetin

The structures of zinc (2), copper(II) (3), and calcium (4) complexes with trans-2R,3R-dihydroquercetin (1) have been elucidated by IR, 2D NMR, mass spectrometry DART techniques, term gravimetric analysis using data from elemental and microscopic energy dispersive X-ray analyses. The redox properties of complexes 2–4 were studied by cyclic voltammetry
