Abstract
The new pyrimidyl- and naphthyridyl-modulated pentapyridyltetramine ligand (H3N9-2pm) and its linear nona- and octanickel chain complexes were successfully synthesized. The nonanickel complex [Ni 9(μ9-N9-2pm)4Cl 2](PF6)2 (1) contains two fully delocalized, mixed-valence [Ni2(napy)4]3+ units. Magnetic measurements performed on the defective octanu-clear complex [Ni 8(μ8-N9-2pm)4Cl 2](PF6)2 (2) demonstrate that the metal chain provides a pathway of magnetic superexchange coupling over the extended metal atom chain (EMAC). © Wiley-VCH Verlag GmbH & Co.
