A new Co(II) coordination polymer [Co(Hdpa)2(dpdo)(H2O)2] (1) (H2dpa = 2,2′-biphenyldicarboxylic acid, dpdo = 4,4′-bipyridine-N,N′-dioxide) has been synthesized and characterized by IR and UV/Vis spectroscopy, elemental analysis, and single-crystal X-ray structure analysis. The Co(II) atom has a distorted octahedral coordination environment with a set of oxygen donors from two Hdpa− ligands, two dpdo ligands and two coordinated water molecules. Adjacent cobalt centers are bridged by dpdo ligands thereby generating a chain. In the solid state, the chains further interact with each other and form a 3D supramolecular network via C–H··· π interactions and multiform hydrogen bonds.
