摘要：
The reactions of functionalized lithium CF3-beta-diketonate (LiL) with europium(III) and terbium(III) chlorides in acetonitrile afford heterobimetallic complexes with the general formula [LiL-nL(4)(H2O)](CH3CN) (Ln = Eu (IIIa) and Tb (IIIb)). It is found that Ln-Li tetrakis-beta-diketonates can also be prepared by the crystallization from acetonitrile of the previously synthesized complexes [(LnL(3))(LiL)(MeOH)] (I) and [(LnL(3))(LiL)(H2O)] (II). For the first time, the single crystals of the compounds in a series of Ln-Li tetrakis-beta-diketonates are characterized by X-ray diffraction analysis (CIF files CCDC nos. 1973632 (IIIa) and 1973633 (IIIb)). The photoluminescence properties of the synthesized heterometallic complexes in the solid state are studied.
