Reaction of Eu(NO 3) 3·6H 2O with 1,3-bis(1,3-dimethyl-1H-pyrazol-4-yl)-1,3-propanedione (HL) in the presence of NaOH affords the complex compound [Na(H 2O) 4] [EuL 4]·0.775CH 2Cl 2 (I). The spectral (UV, IR, 1H NMR spectroscopy), and thermo-luminescent (TG-DSC-MS) properties of the complex I, as well as its fragmentation at the laser desorption ionization (LDI-MS) were studied. © Pleiades Publishing, Ltd., 2011.
