The bimetallic hexanuclear cluster[Mn_4Ni_2O_2(Cl-Sao)_6(CH_3OH)_8]10CH_3OH(1) was synthesized.Single-crystal X-ray analysis reveals that 1 consists of two[Mn_2Ni(μ_3-O)(CI-Sao)_3]subunits linked together via two pairs of long Ni-0 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 Mn~(III) and Ni~(II) ions exchange magnetic coupling through O~(2-),O~-_(phenolate) and-N-Obridges.The magnetic properties of the cluster have been investigated.

Each Mn and Ni center achieves six-coordination with axial methanol molecules. The spin centers of the Mn ~ (III) and Ni ~ (II) ions exchange magnetic coupling through O ~ (2 -), O ~ -phenolate and-N-Obridges.The magnetic properties of the cluster have been investigated.
