  Novel europium and gadolinium compounds in the lanthanide(III) oxydiacetate series

  摘要：

  Three new lanthanide oxydiacetate compounds have been prepared and their structures determined by single crystal X-ray methods: {[Ln(2)(oda)(3)(H2O)(2)]. 5H(2)O}n (Ln = Eu, Gd) and [Eu(oda)(Hoda)(H2O)]. 2H(2)O. The former are orthorhombic and Ama2, with LnO(8) and LnO(9) cores bridged by anti-anti carboxylate ligands and the latter is mononuclear containing a EuO9 core. Luminescence spectra of the europium complexes in the solid state are presented. (C) 2000 Elsevier Science S.A. All rights reserved.

  Heterometallic compounds comprising copper(II) and rare-earth cations with carboxylate groups of the 2,2′-oxydiacetato as the connecting ligands, have been investigated. Five isostructural polymers [Cu3Ln2(oda)6(H2O)6}·12H2O]n (Ln = Y (1), Gd (2), Eu (3), Nd (4) and Pr (5)) have been obtained and their structures determined by X-ray diffraction methods. The Ln(III) cations in 1 to 5 are coordinated by six carboxy and three ether oxygen atoms in the tricapped trigonal prism arrangement and the Cu(II) cations are bonded to four carboxy oxygens and two apical aqua ligands in a distorted octahedral geometry. The magnetic behaviors of these complexes show very weak antiferromagnetic interaction in the solid.

  我们研究了以 2,2â²-氧二乙酸根的羧酸基为连接配体，由铜（II）和稀土阳离子组成的杂金属化合物。研究人员获得了五种等结构聚合物[Cu3Ln2(oda)6(H2O)6}Â-12H2O]n（Ln = Y (1)、Gd (2)、Eu (3)、Nd (4)和 Pr (5)），并通过 X 射线衍射方法确定了它们的结构。1 至 5 中的 Ln（III）阳离子由六个羧基氧原子和三个醚氧原子配位，呈三顶三棱柱排列；Cu（II）阳离子与四个羧基氧原子和两个顶端水配体成键，呈扭曲的八面体几何结构。这些配合物的磁性表现显示出固体中非常微弱的反铁磁相互作用。
