Synthesis and crystal structure of [Na(H2O)4] [EuL4] · 0.775CH2Cl2 (HL = 1,3-Bis 1,3-dimethyl-1H-pyrazol-4-yl)-1,3-propanedione)
[Na(H2O)4][EuL4] · 0.775CH 2Cl2 (I) has been synthesized by the reaction of Eu(NO 3)3 · 6H2O 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) Å3, ρ calcd = 1.427 g/cm3, μ(MoKα) = 1.140 mm-1, space group P4/n, Z = 2. The structural units forming a crystal of compound I are [EuL4]- complex anions, [Na(H2O) 4]+ cations, and CH2Cl2 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.
