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