A nine-coordinated dysprosium(iii) compound with an oxalate-bridged dysprosium(iii) layer exhibiting two slow magnetic relaxation processes

Abstract

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.
