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

Abstract A new 2D polymer, {[Mn 6 Na 3 (μ 6 -O)(thme) 4 (PhCO 2 ) 6 (μ-H 2 O) 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 {Mn 6 Na 3 } 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 {Mn 6 Na 3 } clusters.
