A new adamantane-like tetranuclear manganese(III) complex based on flexible schiff-base Ligand: Synthesis, crystal structure and magnetic property

Abstract

A new tetranuclear Mn(III) complex [Mn III 4 (sae) 4 (μ3-O)(μ1,1-N3)(OH)(H 2 O) 2 ]•H 2 O (1) (H 2 sae = 2-salicylideneamino- 1-ethanol) has been synthesized by the reaction of MnCl 2 • 4 H 2 O, H 2 sae and sodium azide in the mixed solvent of methanol, acetonitrile and water. The X-ray diffraction analysis shows that the four Mn(III) ions in complex 1 have a unique adamantine arrangement, whereas the coordination environment of each Mn(III) ions is different. Magnetic studies indicate that complex 1 manifests antiferromagnetic behaviors. The magnetic susceptibilities of complex 1 have been fitted by two magnetic models based on the suitable analysis of its magnetic structural topology.
