The complex was characterized by ¹H-NMR, positive FAB-mass, and Elemental Analysis. The exact molecular structure of 2a was determined by single crystal X-ray diffraction with the monoclinic space group Cc (centrosymmetric, No.13). The large cavity sizes of the complex 2a facilitated the inclusion of water and benzene solvate molecules. The other two different crystals 2b, 2c having two water molecules and one benzene moleculewere obtained by the crystallization in different solvents and the exact molecular structures were determined by single crystal X-ray diffraction analysis with space groups P2₁/n (centrosymmetric, No.14), and P2₁/n (centrosymmetric, No.14), respectively. The eight coordinate structures of the complexes in the three crystals were slightly different due to the crystal packing and the existence of the solvent %K Tetrakis Europium Complexes %K Luminescence %K < %K i> %K ¦Ā< %K /i> %K -Diketone Ligands %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=80188
