A new manganese(II) terephthalate layer with 6-connected hxl topology and antiferromagnetic property

A novel two-dimensional (2D) Mn(II) coordination polymer [Mn1.5(H2bdc)1.5(DMA)2] (1; H2bdc = terephthalic acid; DMA = N,N′-dimethylacetamide) based on trinuclear manganese subunit has been solvothermally prepared and structurally characterized by single-crystal X-ray diffraction. Compound 1 exhibits a rare layered structure with 6-connected hxl topology constructed from the trinuclear Mn3(COO)6 units, and further stacking of layers leads to a 3D supramolecular framework. The thermalgravimetric behavior and magnetic property of 1 have been also investigated. The magnetic susceptibility measurements reveal that the compound exhibits antiferromagnetic coupling interactions.
