Role of anions in radiation-induced transformations of 18-crown-6 complexes with barium salts: simulating the effects of extraction mechanism on radiation stability of macrocyclic extractants
Complexes of 18-crown-6 with BaCl 2 , Ba(NO 3 ) 2 and Ba(NTf 2 ) 2 salts were synthesized and irradiated with X-rays to simulate the radiation degradation of a macrocyclic component of extractants based on crown ether solutions in commonly used solvents. Structures and post-irradiation transformatio...
