Two diastereopure ligands, N,N′-bis(4-pyridyl)idene(1R,2R)- diaminocyclohexane (L 1 ) and N,N′-bis(3-pyridyl)idene(1R,2R)-diaminocyclohexane (L 2 ), have been synthesized and characterized. The interaction of L 1 with Ag(I) ions and L 2 with Cd(II) ions has been investigated. The structure of {[Ag(L 1 ) 2 ](CF 3 SO 3 )·4H 2 O}...
A new category of dinucleating macrocyclic Schiff base ligands with ring sizes from 34- to 52-membered have been synthesised employing metal template procedures involving the reaction of o-phenylenediamine with a series of α,ω-bis(3′-hydroxy-4′-formylphenyloxy)alkanes in the presence of calcium(II), barium(II) or manganese(II). The latter cations act as ‘transient’ templates for formation of the corresponding...
