Structure and magnetic property of bimetallic hexanuclear cluster based on 5-chlorosalicylaldehyde oxime

The bimetallic hexanuclear cluster [Mn4Ni2O2(Cl-Sao)6·(CH3OH)8]·10CH3OH (1) was synthesized. Single-crystal X-ray analysis reveals that 1 consists of two [Mn2Ni(μ3-O)(Cl-Sao)3] subunits linked together via two pairs of long NiO bonds involving two oximate oxygen atoms and two phenolate oxygen atoms. Each Mn and Ni center achieves six-coordination with axial methanol molecules. The spin centers of the MnIII and NiII ions exchange magnetic coupling through O2−, O−phenolate and NO bridges. The magnetic properties of the cluster have been investigated.
