[Na(H 2O) 4][EuL 4] · 0.775CH 2Cl2 (I) has been synthesized by the reaction of Eu(NO 3) 3 · 6H 2O with 1,3-bis(1,3-dimethyl-1H- pyrasol-4-yl)-1,3-propanedione (HL) in the presence of NaOH. Its crystal struc- ture has been solved by X-ray diffraction analysis. Crystals are tetragonal; a = 16.2401(5) Å, c = 11.9113(4) Å, V=3141.50(17) Å 3, ρ calcd = 1.427 g/cm 3, μ(MoKα) = 1.140 mm-1, space group P4/n, Z = 2. The structural units forming a crystal of compound I are [EuL 4] - complex anions, [Na(H 2O) 4] + cations, and CH 2Cl 2 mole- cules. The coordination polyhedron of the Eu atom is an Archimedean antiprism formed by the O atoms of four bidentate chelate ligands L -. © Pleiades Publishing, Ltd., 2011.

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.
