| Abstract: | A 4d–4f heterometallic coordination polymer, AgLa(pydc)2]·3H2O ( 1 ) (H2pydc = pyridine‐3,4‐dicarboxylic acid), has been synthesized under hydrothermal conditions, and further characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single‐crystal X‐ray diffraction. Complex 1 features a three‐dimensional (3D) framework containing one‐dimensional (1D) channels occupied by free water molecules, which is constructed from 1D inorganic heterometallic chains and linear pydc linkers. To the best of our knowledge, complex 1 represents a rare example of 3D open‐framework 4d–4f heterometallic coordination polymer. Moreover, after removal of the water molecules from complex 1 , the remaining material has high thermal stability and good adsorption behavior towards nitrogen gas. |
