A Solvent-Stable Zinc(II)–Gadolinium(III) Metal–Organic Framework Assembled with Furan-2,5-Dicarboxylic Acid: Synthesis, Crystal Structure and Magnetic Property
2019
A novel three-dimensional 3d–4f metal–organic framework (MOF), {[(CH3)2NH2]2[Zn2Gd2(FDA)6(DMF)2]·2DMF}n (Zn–Gd) (H2FDA = furan-2,5-dicarboxylic acid) assembled with furan-2,5-dicarboxylic acid has been isolated and characterized by infrared spectra, elemental analysis, thermogravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction. Structure analysis indicates this MOF is an interesting three-dimensional 8-connected bcu body centered cubic topological net. Moreover, Zn–Gd MOF shows a tolerance towards moisture and the corresponding solvents, demonstrating the excellent chemical stability. The magnetic property of Zn–Gd MOF suggests a weak antiferromagnetic coupling interaction between adjacent Gd(III) ions in Zn–Gd MOF.
