The new pyrimidyl- and naphthyridyl-modulated pentapyridyltetramine ligand (H(3)N(9)-2pm) and its linear nona- and octanickel chain complexes were successfully synthesized. The nonanickel complex [Ni(9)(mu(9)-N(9)-2pm)(4)Cl(2)](PF(6))(2) (1) contains two fully delocalized, mixed-valence [Ni(2)(napy)(4)](3+) units. Magnetic measurements performed on the defective octanu-clear complex [Ni(8)(mu(8)-N(9)-2pm)(4)Cl(2)](PF(6))(2) (2) demonstrate that the metal chain provides a pathway of magnetic superexchange coupling over the extended metal atom chain (EMAC).
