摘    要:本文报道了一个新的有机双膦酸铜化合物Cu3{(C5NH11)C(OH)(PO3)2}2(H2O)4·4H2O(1)的合成及结构。该化合物呈梯子型双链结构,由Cu(1)O5四方锥体和Cu(2)O6八面体通过{PO3C}四面体以共顶点方式连接而成。相邻的双链以几乎相互垂直的方式堆积,通过氢键作用形成了具有孔道的三维超分子网络结构,晶格水分子填充其中。磁性研究表明在铜离子间存在反铁磁相互作用。

关 键 词:    有机双膦酸    梯子双链结构    磁性

Abstract:This paper reports the synthesis and crystal structure of a new copper diphosphonate C(OH)(PO3)2}2(H2O)4·4H2O (1) based on 1-hydroxy-1-(piperidin-4-yl)methylidenebisphosphonic acid (hpdpH4).It shows an infinite ladder-like double chain structure in which the Cu(l)O5 square pyramids and Cu(2)O6 octahedra are linked by coiner sharing {PO3C} tetrahedra.The double chains are packed in almost inter-perpendicular manner,forming a three-dimensional hydrogen-bonded supramolecular network.The lattice water molecules reside in the channels.The magnetic studies reveal that dominant antiferromagnetic interactions are mediated between the Cu(Ⅱ) ions.
Keywords:copper  diphosphonate  ladder-like chain structure  magnetic property
