A new tetranuclear Mn(III) complex [MnIII 4(sae)4(μ3-O)(μ1,1-N3)(OH)(H2O)2]·H2O (1) (H2sae = 2-salicylideneamino- 1-ethanol) has been synthesized by the reaction of MnCl2·4H2O, H2sae 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.
