Three azido‐bridged coordination polymers, namely [Mn(L 1 )(N 3 ) 2 ] n ( 1 ), [Mn(L 2 )(N 3 ) 2 ] n ( 2 ), and [Mn(L 3 )(N 3 ) 2 ] n ( 3 ) [L 1 = N ‐(2‐pyridylmethylene)methylamine, L 2 = N ‐(2‐pyridylmethylene)ethylamine, and L 3 = N ‐(2‐pyridylmethylene)octylamine], have been synthesized with Schiff‐base co‐ligands with flexible tails, and their structures and magnetic properties characterized. Complex 1 is composed of one‐dimensional, uniform chains with double end‐on (EO) azido bridges, complex 2 consists of (6,3) net layers in which double EO azido‐bridged dimers are interlinked by single end‐to‐end (EE) azido bridges, and complex 3 contains chains of Mn II ions bridged by alternating double EO and double EE azido bridges. Magnetically, 1 is a metamagnet built of ferromagnetic chains, 2 exhibits weak ferromagnetism due to spin canting, and 3 shows alternate ferro‐ and antiferromagnetic intrachain interactions.
