(L)Mn(OTf)two Based on ref [29], Mn(OTf)2 (0.875 g, 2.four mmol) was added to a answer of L (0.54 g, 2 mmol) in 3 mL of acetonitrile. The mixture was stirred at space temperature for 15 h as well as the solvent was removed beneath vacuum. The light grey powder obtained was washed twice with diethyl ether and right after recrystallization by diffusion of diethyl ether into a option of your solution in acetonitrile, (L)Mn(OTf)2 (0.85 g, 68 yield) was obtained as a white powder. Anal. Calc. for C18 H22 F6 MnN4 O6 S2 : C, 34.68; H, 3.56; N, 8.99. Located: C, 34.68; H, three.42; N, 8.95. 3.3.three. (L)Mn(p-Ts)2 A answer of Ag(p-Ts) (1.34 g, four.8 mmol) in 5 mL of H2 O was added to a option of (L)MnCl2 (0.79 g, 2 mmol) in five mL of H2 O along with the mixture was stirred at space temperature for 15 h. Immediately after removal in the AgCl precipitate by filtration, the solvent was removed under vacuum. Recrystallization in the crude solution in absolute ethanol afforded (L)Mn(p-Ts)2 (0.96 g, 72 yield) as a grey solid. Anal. Calc. for C30 H36 MnN4 O6 S2 : C, 53.97; H, five.43; N, eight.39.

[(L)FeCl2 ](FeCl4 ) FeCl3 ,6H2 O (1.08 g, four mmol) was added to a remedy of L (0.54 g, two mmol) in five mL of acetonitrile. Right after 15 min, a red precipitate appeared as well as the mixture was stirred for 15 h at area temperature. After filtration in the red strong recrystallization in CH3 CN afforded [(L)FeCl2 ](FeCl4 ) (0.93 g, 73 yield) as a red solid. Anal. Calc. for C16 H22 Cl6 Fe2 N4 : C, 32.31; H, 3.73; N, 9.42.

SiO2 Particles in EtOH (SiO2 (E)) Based on ref [64], 72 mL (4 mol) of H2 O, 60 mL of ammonic option (28 wt) had been mixed in 630 mL (ten.79 mol) of absolute ethanol at space temperature. A measure of 40 mL (0.18 mol) of tetraethylorthosilicate (TEOS) was added for the option. A white suspension appeared. The mixture was stirred at 50 C for 6 h. Then the strong was washed with absolute ethanol 5 times and collected by centrifugation. SiO2 (E) particles have been dried under vacuum at 120 C overnight. A white powder was obtained.
