文摘

NiO nanoparticles were in situ formed in a new metal–organic framework (MOF), [Ni₃(pyip)₂(HCOO)₂(H₂O)₂]_n [1; H₂pyip = 5-(pyridine-4-yl)isophthalic acid], which was characterized by Fourier transform infrared spectroscopy, elemental analysis, thermogravimetric analysis, transmission electron microscopy, and powder and single-crystal X-ray diffraction. The MOF 1 shows a 3,6-connected three-dimensional rtl topology network with a topological symbol of (4.6²)₂(4².6¹⁰.8³). Magnetic property studies showed that the combination of NiO nanoparticles within the magnetic MOF leads to the occurrence of long-range magnetic ordering below a critical temperature of 18 K.
