The manganese(II) coordination polymer [Mn(2‐Meimi) 2 (μ 1,1 ‐N 3 ) 2 ] n · n H 2 O ( 1 ) (Meimi = 2‐methyl‐imidazole) with μ 1,1 ‐N 3 (end‐on, EO) bridge was synthesized by hydrothermal reaction of MnCl 2 , NaN 3 , and Meimi. It was characterized by elemental analysis, IR spectroscopy, powder XRD, and magnetic measurements. Single crystal X‐ray analysis revealed that compound 1 features a one‐dimensional (1D) catenated structure and the 1D chains are further connected by strong intermolecular hydrogen bonds to a 3D supramolecular framework. Variable‐temperature magnetic susceptibility measurements revealed that compound 1 displays dominant ferromagnetic interactions through the μ 1,1 ‐N 3 (end‐on, EO) bridging mode.
