A new Mn(III) coordination polymer, [MnL] n , based on a salicylamide imine multidentate ligand, 1-(2-hydroxy-benzamido)-2-(2-hydroxy-5-nitrobenzylideneamino)-ethane ( H 3 L ) was prepared. Single crystal analysis revealed that the title compound was a herringbone like Mn(III) coordination polymer where deprotonated ligand L 3– acted as a pentadentate ligand with amide group being bridge to connect two Mn(III) centres. Magnetic susceptibilities indicates that [MnL] n exhibits an antiferromagnetic coupling with a long-range canted antiferromagnetic ordering and metamagnetic behavior at low temperatures. And the photophysical determination shows that [MnL] n also displays strong long life red luminescence. The results presented herein indicates [MnL] n appears to be an excellent candidate for multifunctional material as a result of its high thermal stability, interesting magnetic and luminescent properties.
