38% With sodium hydroxide In ethanol; water at 40 - 50℃; for 4h; 2.2. Synthesis Stock 0.5M solution of EuCl3 was prepared by the treatment of Eu2O3(4.400 g, 12.50 mmol) by minimum amount of concentrated HCl in aquartz crucible. The resulting solution was evaporated to dryness at 90 °Cand the residue was dissolved in a minimum amount of distilled water.After that, the solution was transferred quantitatively to a volumetric flaskand the volume was adjusted to 50 mL. This solution was then kept in apolypropylene flask. To a stirred warm (40 °C) solution of the ligand(3 mmol) and (1 mmol) bathophenanthroline (0.33 g) in 30 mL of ethanol,2 mL of an 0.5M aqueous solution of EuCl3 (1 mmol) were added dropwise,followed by careful addition of 3 mL (3 mmol) of an 1.0M NaOHsolution in water until the pH of the mixture reached 6-7. The mixture washeated at 50 °C during 4 h in a closed flask and cooled. Further operationsdepended upon the properties of the reaction products.

Complex a Neodymium oxide Nd2O3 (99.99%, 2.102 g, 6.25 mmol) was dissolvedin a minimum amount of concentrated HCl (high purity grade),and the solution was evaporated to dryness on a water bath andtransferred to a volumetric flask. The volume was brought to 25 mLwith deionized water to obtain a 0.5 M stock solution of NdCl3.Ligands 1-(1,3-dimethyl-1H-pyrazol-4-yl)-4,4,4-trifflluorobutane-1,3-dione (HL1) (0.351 g, 1.5 mmol) and 1,10-phenanthroline (0.09 g,0.5 mmol) were dissolved in warm ethanol (8 mL); 0.5 M solution ofNdCl3 (1 mL) followed by 1 M NaOH (1.5 mL) were added dropwisewith stirring. The greenish-blue solution that formed was filtered,stored at 55 C for 2 h, and left to stand for 24 h at room temperature.Then, the solvent was evaporated to dryness at reduced pressure, andthe residue was extracted with 30 mL of warm acetone. The solutionwas filtered and left in an open beaker at room temperature. Afterevaporation of the solvent, the glassy residue was re-dissolved in aminimum amount of warm MeCN. Crystallization was induced bycareful addition of an equal volume of Et2O with rubbing the wallsby a glass rod. The pale greenish powder was separated, washed withhexane and dried at reduced pressure (50 C and 0.1 Torr) to constantweight. The yield was 0.347 g (67%).For C39H32F9N8NdO6 (FW 1023.95)Calcd., %: C, 45.75; H, 3.15; N, 10.94; Nd, 14.09.Found, %: C, 45.91; H, 3.23; N, 11.09; Nd, 14.24.IR (cm-1): 1657, 1540, 1465, 1345.NMR assignment: 1H NMR (CD2Cl2), (ppm): -0.6 (br. s, 9H, C-CH3), 1.26 (br. s, 2H, 2H-phen), 3.92 (br. s, 9H, N-CH3), 5.89 (br. s,2H, 3H/4H-phen), 6.15 (br. s, 2H, 3H/4-phen), 6.52 (br. s, 2H, 6Hphen),9.46 (br. s, 3H, 5H-pyr), 10.88 (br. s, 3H, CH-acac). 19F{1H}NMR (CD2Cl2), (ppm): -75.68 (s, CF3).
