摘要: 通过水热方法,合成了一个杂金属的配位聚合物{[NdZn(H₂pimda)₃(Hpimda)(H₂O)₂]·H₂O}_n(1),(H₃pimda=2-丙基-1H-4,5-咪唑二酸),并对其结构和磁性质进行了研究。结构分析结果表明配合物1的晶体属于单斜晶系,P2₁/c空间群。配合物1是由配体2-丙基-1H-4,5-咪唑二酸连接而成的二维层状结构,该二维层通过氢键延伸为三维超分子结构。磁性研究表明,配合物1中相邻钕离子间存在着反铁磁相互作用。

Abstract: Anovel 3d-4f heterometallic coordination polymer, namely, {[NdZn(H₂pimda)₃(Hpimda)(H₂O)₂]·H₂O}_n (1), (H₃pimda=2-propyl-1H-imidazole-4,5-dicarboxylic acid) has been hydrothermally synthesized by using Nd₂O₃, Zn(NO₃)₂·6H₂O and H₃ pimda as raw materials, and characterized by elemental analysis, IR, TG analysis and single crystal X-ray diffraction. The complex 1 crystallizes in the monoclinic system, space group P2₁/c with a=1.19078(2) nm, b=1.30784(3) nm, c=2.74070(5) nm, β=97.9300(10)°, V=4.22741(14) nm³, D_c=1.652 g·cm^-3, Z=4, R=0.0492 and wR=0.1115 (I>2σ(I)). Polymer 1 possesses two-dimensional (2D) network, which further build three-dimensional (3D) supramolecular architecture via N-H…O hydrogen-bonding interactions. Variable temperature magnetic susceptibility studies reveal that complex 1 displays weak antiferromagnetic coupling between the neighboring Nd(Ⅲ) ions. CCDC: 906826.
