NiO纳米颗粒在新的金属有机框架（MOF）中原位形成，[Ni-3(pyip)(2)(HCOO)(2)(H2O)(2)](n) [1；H(2)pyip = 5-（吡啶-4-基）间苯二甲酸]，通过傅里叶变换红外光谱、元素分析、热重分析、透射电镜、粉末和单晶x射线衍射等手段对其进行了表征。MOF 1为3,6连通的三维rtl拓扑网络，拓扑符号为（4.6(2)）(2)(4(2).6（10).8(3)）。磁性能研究表明，NiO纳米颗粒在磁性MOF内的结合导致在18 K以下的临界温度下发生长程磁有序。
NiO nanoparticles were in situ formed in a new metalorganic framework (MOF), [Ni-3(pyip)(2)(HCOO)(2)(H2O)(2)](n) [1; H(2)pyip = 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 (4.6(2))(2)(4(2).6(10).8(3)). 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.
