A 2D oxalate-bridged dysprosium(III) compound, formulated as [Dy(C2O4)1.5(H2O)3]n·2nH2O (1), has been hydrothermally isolated. As for compound 1, structural analysis reveals that the nine-coordinated Dy(III) ions reside in a slightly distorted tricapped trigonal prism. Under an applied magnetic field of 700 Oe, the compound was magnetically characterized as a new example that two slow relaxations of the magnetization processes can be observed in a 2D oxalate-bridged dysprosium(III) layer.
一种二维草酸根桥联的镝（III）化合物，化学式为[Dy(C₂O₄)₁.₅(H₂O)₃]ₙ·2nH₂O（1），已通过水热法分离得到。对于化合物1，结构分析表明九配位的Dy(III)离子位于一个轻微扭曲的三帽三棱柱中。在700奥斯特的外加磁场下，该化合物的磁性特征表明，在二维草酸根桥联的镝（III）层中可以观察到磁化过程的两种慢弛豫，这是一个新的例子。
