A new magnetic coordination polymer, [Fe(bipy)(im)2] (bipy = 4,4-bipyridine and im = imidazole), has been synthesized in a solvent-free reaction. Structural analysis reveals a pillared 3D coordination polymer composed by neutral layers, formed by iron(II) and imidazolate linkers, interconnected by bipy ligands which serve as pillars. Magnetic measurements show that the material magnetically orders at low temperatures (Tc = 14.5 K) as a weak ferromagnet, likely due to a spin canting.
一种新型磁性配位聚合物[Fe(bipy)(im)₂](bipy = 4,4-联吡啶,im = 咪唑)已在无溶剂反应中合成。结构分析表明,它是一种柱状三维配位聚合物,由中性层组成,这些中性层由铁(II)和咪唑盐连接体形成,通过充当支柱的联吡啶配体相互连接。磁性测量表明,该材料在低温下(Tc = 14.5 K)呈现弱铁磁有序,这可能是由于自旋倾斜所致。
