[0041] Example 1:
[0042] take ligand L 1 (0.202g, 0.400mmol) was dissolved in 20mL of absolute ethanol and placed in a 50mL round-bottomed flask, added containing Mn(OAc) 2 ·4H 2 O (0.049g, 0.200mmol) in 20mL ethanol solution, heated to reflux for 4h, after the reaction was completed, the reaction solution was cooled to room temperature, and then NH was added to the reaction solution 4 PF 6 (0.082g, 0.500mmol), continue to heat to reflux for 2h to precipitate a red solid, filter while hot, filter under reduced pressure to collect the filter cake, recrystallize with absolute ethanol to obtain the target product Mn10.206g, a red solid, yield 75.90% (calculated according to the amount of ligand, the same below).
