A New Adamantane-like Tetranuclear Manganese(III) Complex Based on Flexible Schiff-base Ligand: Synthesis, Crystal Structure and Magnetic Property

A new tetranuclear Mn(III) complex [Mn-4(III)(sae)(4)(mu(3)-O)(mu(1,1)-N-3)(OH)(H2O)(2)]center dot H2O (1) (H(2)sae = 2-salicylidene-amino-1-ethanol) has been synthesized by the reaction of MnCl2 center dot 4H(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.
