N2 - Three azido-bridged coordination polymers, namely [Mn(L1)- (N3)2]n (1), [Mn(L2)(N 3)2]n (2), and [Mn(L3)(N 3)2]n (3) [L1 = N-(2- pyridylmethylene)methylamine, L2 = N-(2-pyridylmethylene)ethylamine, and L3 = 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.
