Synthesis and Characterization of Some New Complexes of Magnesium (II) and Zinc (II) with the Natural Flavonoid Primuletin

Two new metal complexes formulated as [Mg(L)(2)(H(2)O)(2)]·H(2)O (1) and [Zn(L)(2)(H(2)O)(2)]·0.5H(2)O (2), where HL = 5-hydroxyflavone (primuletin), have been synthesized and characterized by elemental and thermal analyses, molar conductance, IR, UV-Vis, (1)H- and (13)C-NMR, fluorescence and mass s...

Descripción
Sumario:Two new metal complexes formulated as [Mg(L)(2)(H(2)O)(2)]·H(2)O (1) and [Zn(L)(2)(H(2)O)(2)]·0.5H(2)O (2), where HL = 5-hydroxyflavone (primuletin), have been synthesized and characterized by elemental and thermal analyses, molar conductance, IR, UV-Vis, (1)H- and (13)C-NMR, fluorescence and mass spectra. In solid state, complexes had shown higher fluorescence intensities comparing to the free ligand, and this behavior is appreciated as a consequence of the coordination process.
