Transport of metal salts; encapsulation of anions in dinuclear Cu(ii) complexes [Cu2L2SO4]SO4 and [Cu2L2BF4](BF4)3, where L = 2,2’-[1,6-hexanediylbis[(methylimino)methylene]]bis[4-tert-butyl-6-(phenylazomethinyl)phenol]
Abstract
Linking salicylaldimine units with a 2,9-diazadecane strap in high yields via a simple Mannich condensation generates a
