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

Abstract

A novel two-dimensional (2D) Mn(II) coordination polymer [Mn 1.5 (H 2 bdc) 1.5 (DMA) 2 ] ( 1 ; H 2 bdc = 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 Mn 3 (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. Presented here is a novel two-dimensional (2D) Mn(II) coordination polymer constructed from trinuclear manganese subunits, which exhibits a rare layered structure with hxl topology and antiferromagnetic property. ► A novel two-dimensional (2D) Mn(II) coordination polymer constructed from trinuclear manganese subunits. ► A rare layered structure with 6-connected hxl topology. ► Antiferromagnetic coupling interactions between Mn centers in the trinuclear Mn unit.
