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 (μ 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 octanuclear complex [Ni 8 (μ 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).
