Synthesis, Crystal Structure, and Thermal Analysis of a New Dy(III) Compound Based on Pyridinecarboxylate Ligand

Abstract

A new compound, namely [Dy4(L)6(H2O)4]n (1 H2L = 5-(pyridin-4-ylmethoxy)-isophthalic acid), has been hydrothermally synthesized and further characterized by the single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy. Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in monoclinic P21/n space group with a = 24.0566(5), b = 14.3950(3), c = 26.0162(6), and β = 92.146(2)°. In the compound, there are two different 1D chains constructed by L2− ligands and Dy(III) ions, which are further bridged by the L2− ligands into a complicated 3D framework.
