General procedure: [(C^N)2Ir(mu-Cl)]2 (small excess) and N^N ligand in CH2Cl2/CH3OH (20/4 mL) were stirred overnight at 40 C to give yellow/orange solution. It was evaporated. The residue was purified by column chromatography (silica, 20-25 g). Elution with 2.0-4.0% CH3OH in CH2Cl2 removed the impurities. Elution with 4.0-5.0% CH3OH in CH2Cl2 recovered the product as yellow or orange fraction. The product was preceded and/or followed by coloured/luminescent impurity fractions. The desired fractions were evaporated. The product was dissolved in CH3OH (4 mL), and added drop-wise to a stirred aqueous solution of KPF6 (1-1.3 g, 5.4-7.1 mmol, in 30 mL of water, large excess; Alfa Aesar) in order to convert the complex to a hexafluorophosphate salt. The resulting suspension was stirred for 30 min and filtered. Washed with water and ether. Anal. Calc. for C48H30F12IrN4P (MW 1113.95): C, 51.75; H, 2.71; N, 5.03. Found: C, 52.07; H, 2.84; N, 4.66%

General procedure: The synthetic route of binary and ternary europium complexes C1-C5 is demonstrated in Scheme 2. A solution of EFBA (3 mmol) in ethanol was added dropwise to the aqueous solution of europium nitrate (1 mmol) with constant stirring on magnetic stirrer at room temperature. pH of the resulting mixture was set between 6-7 by using dilute NaOH (0.05 M) and white color precipitates were obtained. The resulting precipitates were vaccum filtered along with washing of water and ethanol to remove the unreacted ligand and then dried in vaccum desiccator to obtain the white powder of Eu(EFBA)3(H2O)2 (C1) complex. Complexes C2-C5 were prepared by the same procedure as adopted for the synthesis of complex C1 but in addition to the reaction mixture of EFBA (3 mmol) and europium nitrate (1 mmol) there is extra addition of ethanolic solution of neo (1 mmol), batho (1 mmol), phen (1 mmol), and bipy (1 mmol) for the synthesis of ternary europium complexes C2-C5, respectively., 1662-01-7

General procedure: In a ethanolic solution of CHME (0.82 g, 3 mmol) add an aqueous solution of Eu(NO3)3*H2O (0.33 g, 1 mmol) was added with constant stirring on magnetic stirrer. The solution was neutralized with 0.05 M NaOH solution and adjusted pH of mixture 7-8. The mixture was stirred for 3 h at 35 C and then allowed to stand for 1 h. During stirring white precipitates appeared, which were filtered and washed with doubly distilled water and then with ethanol to remove the free ligand, after that dried in air and then in vacuum desiccators. Finally the complex was dried at 50 C in hot air oven to obtain the complex. The obtained complex Eu(CHME)3*2H2O was white power with 86 %yield.
