An average NiNNi angle of only 84° is found in the end‐on bridges in complex 1 . This small angle possibly explains the antiferromagnetic coupling of the nickel centers in 1 . For more than 20 years it has been assumed that end‐on coordination should lead to ferromagnetic coupling. The complex occurs as one‐dimensional chains in the solid state.\documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$$[{\rm Ni}({\rm N}_3)_2({\rm temeda})]_n\quad{\bf 1}$$\end{document}
