Popis: | Three novel multidentate long-chained oligo-α-aminopyridine ligands, nonapyridyloctaamine ( 1 , npoa ), decapyridylnonaamine ( 2 , dpna ), and undecapyridyldecaamine ( 3 , upda ) were synthesized successfully by tandem Pd-catalyzed cross-coupling aminations. The helical structures of protonated ligand npoa { 4 , [H4· npoa ](SO3CF3)4} and the related dinuclear complexes 5–10 were synthesized and characterized by X-ray diffractions. |
