An Mn(Ii) Cluster-Based Coordination Framework Derived From Ac(3)Symmetric Ligand: Synthesis, Structure, And Magnetic Properties

A new coordination framework {[Mn-7(L)(4)(OH)(2)(H2O)(4)(DMA)(4)]center dot 8H(2)O center dot 6DMA}(n)(H3L= 3,3 ',3 ''-[1,3,5-benzenetriyltris(carbonylimino)]tris(benzoate); DMA =N,N-dimethylacetamide) is synthesized under mixed solvothermal conditions. Structural analysis reveals that this complex possesses a three-dimensional framework with (3,10)-ctopology based on different [Mn-6] clusters. Moreover, magnetic investigations suggest that intra-cluster Mn(II) ions exhibit antiferromagnetic coupling.
