In the cases of lanthanum(III) and cerium(III), homoleptic complexes [(LnL3)2] are isolated (CIF files CCDC nos. 2031097 (Ia) and 2031102 (Ib)). The reaction of LiL with praseodymium(III) nitrate gives the new trimetallic structure [(LiPrL3)(LiL)(NO3)(H2O)2] (CIF file CCDC no. 2031103 (II)), and the replacement of nitrate by chloride gives [(PrL3)(LiL)(H2O)] (CIF file CCDC no. 2031104 (IIIa)). Regardless of the nature of the anion of the salt in the series from neodymium(III) to ytterbium(III) and yttrium(III), Ln–Li β-diketonates [(LnL3)(LiL)(solv)] (solv is H2O and MeOH) are formed, and their structures are characterized by X-ray structure analysis (CIF files CCDC nos. 2031099 (IIIb), 2031100 (IIIc), 2031098 (IVa), 2031096 (IVc), 2031094 (IVf), 2031101 (IVg), and 2031095 (IVh)). The equilibrium of the diketonate isomeric forms in a solution of deuterated dimethyl sulfoxide is studied by 19F NMR spectroscopy, and the qualitative composition of the polynuclear complexes is determined by mass spectrometry. |
