A lanthanide metal–organic framework (MOF) Yb(BTC)(H2O)·(DMF) (BTC = 1,3,5-benzenetricarboxylate, DMF = N,N-dimethylformamide) was prepared from Yb(NO3)3·5H2O and H3BTC using the solvothermal method and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, N2 adsorption–desorption technology, and temperature-programmed
