In situ hydrothermal decarboxylation was observed during preparing two novel three-dimensional (3D) lanthanide–organic frameworks Ln(2,5-PyDC)(3-PyC)(H2O) (Ln = Nd, Sm; 2,5-H2PyDC = 2,5-pyridinedicarboxylic acid, 3-HPyC = 3-pyridinecarboxylic acid). X-ray crystallographic analyses revealed that both complexes are isomorphous and show an interesting topology. Magnetic study indicated the coupling interaction between Ln3+ ions in both complexes is weak.
In situ hydrothermal decarboxylation reactions play an important role to form two novel (3D) lanthanide–organic frameworks Ln(2,5-PyDC)(3-Py-C)(H2O) (Ln = Nd, Sm; 2,5-H2PyDC = 2,5-pyridinedicarboxylic acid, 3-HPyC = 3-pyridinecarboxylic acid), which can be specified by the Schläfli symbol (42638) as a 3D {4,4}-connected net.Figure optionsDownload as PowerPoint slide
