A new 2D honeycomb-like cluster polymer built by a {Mn6Na3} cluster: Synthesis and magnetic property

A new 2D polymer, {[Mn6Na3(μ6-O)(thme)4(PhCO2)6(μ-H2O)3][OH]}n(1), has been synthesized and characterized by single crystal X-ray diffraction, XRD, IR spectroscopy, thermogravimetric analysis (TGA) and magnetic measurements. Compound 1 has a 2D honeycomb-like structure constructed by heterometallic {Mn6Na3} clusters, which are linked by water molecules cross-bridged between the Na (I) ions of the adjacent clusters. Magnetic property study reveals the existence of antiferromagnetic couplings between Mn (III) ions within the {Mn6Na3} clusters.

A new 2D honeycomb-like polymer based on a {Mn6Na3} cluster has been synthesized by employing mixed ligands of 1,1,1-tris(hydroxymethyl)ethane and benzoic acid under aerobic conditions at room temperature. The DC and AC magnetic properties of the title compound have also been examined.Figure optionsDownload as PowerPoint slideHighlights
