• A new LOF was synthesized.
• Novel (H2O)20 clusters form a one-dimensional chain.
• Complex 1 shows fluorescent emission with green -shifts at 544 nm.
A novel lanthanide coordination polymer, (H2pipz)3[Tb2(pydc)6]·15H2O (1) (where pipz = piperazine and H2pydc = pyridine-2,6-dicarboxylic acid), has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, infrared spectroscopy, element analysis and thermogravimetric analysis. The most interesting structural feature of 1 consists in the occurrence of one-dimensional infinite water chains made up of novel (H2O)20 clusters. 1 is extended into a three-dimensional supramolecular network structure via an extensive net of hydrogen bonds together with π–π stacking interactions. In addition, 1 was demonstrated to display a green fluorescence emission in the solid state at room temperature.
A novel (H2O)20 cluster encapsulated in the lattice voids of the lanthanide coordination polymer, (H2pipz)3[Tb2(pydc)6]·15H2O (where pipz = piperazine and H2pydc = pyridine-2,6-dicarboxylic acid) formed a one-dimensional infinite water chain through hydrogen bonding.Figure optionsDownload as PowerPoint slide
