The metal string complex [Ni 3 (dpa) 4 (ClO 4 )(Cl)] · CH 2 Cl 2 ( 1 ) [dpa = bis(2‐pyridyl)amine] with different axial ligands was synthesized and characterized by elemental analysis, IR, UV/Vis, and fluorescence spectroscopy and TG analysis. The molecular structure was determined by single‐crystal X‐ray analysis and its electrochemical properties were investigated. This metal string complex is the first example with different axial ligands, and in its structure a different structural packing relative to the metal string complex [Ni 3 (dpa) 4 (Cl) 2 ] ( 2 ) with two axial chloride ligands is generated. The intense C–H ··· π interactions observed for 1 provide additional stability. The axial mono‐substitution of Cl – by ClO 4 – in 1 relative to 2 results in one obviously short Ni–Ni distance and a higher stability towards oxidation.
