Abstract

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.
