Each Mn­(III) ion exhibits a characteristic Jahn–Teller elongation along the chain direction. For both compounds, antiferromagnetic interactions between Mn­(III) spins within a chain are transmitted through the azide ligands, together with the apparent occurrence of spin canting at low temperatures. Remarkably, the coupling constants (<i>J</i>) for <b>1</b> and <b>2</b> exceed those reported for end-to-end azide-linked Mn­(III) systems. A systematic magnetostructural relationship based on the torsion angle is established in terms of the torsion angle Mn–N<sub>ax</sub>···N<sub>ax</sub>–Mn (ax = axial) for the first time. 2014-08-04 00:00:00 chain compounds 2O Magnetic Properties Mn azide ligands chain direction 2L Direct Magnetostructural CorrelationThe magnetostructural relationship torsion angle antiferromagnetic interactions
