A new porous coordination polymer, i.e. the two-dimensional layered network {[Cu3(4,4¡ä-bpy)3(¦Ì-OOCH)4(H2O)2](BF4)2(H2O)6}n has been synthesized from Cu(BF4)2¡¤6H2O, 4,4¡ä-bpy and with formate as co-ligand. Single-crystal X-ray diffraction analysis reveals a (4,4) 2D coordination network exhibiting voids that contain the counter-ions and water guest molecules. In addition, the title compound is further stabilized by hydrogen bonds and anion-¦Ð interactions to form an intricate supramolecular framework. The removal and reintroduction of guest water molecules has been explored to better understand the dynamic structural transformation. The coordination compound shows weak catalytic activity in the cyanosilylation of aldehydes.
