A polyoxometalate-based copper(II) inorganic-organic hybrid polymer [Cu(dpdo)2(H2O)4][Na2(Mo8O26)·(H2O)6]·(dpdo)·2H2O (1) (dpdo = 4,4′-bipyridine-N,N′-dioxide) has been synthesized and structurally characterized by IR spectroscopy, elemental analysis, and single-crystal X-ray analysis. The structure is based on two types of polymeric chains, the anionic one constructed by the coordination interaction between the [β-Mo8O26]4− cluster anions and [Na2]2+ units, and the cationic one formed through the
coordination interaction of Cu(II) atoms and dpdo ligands. In addition, there are multiform hydrogen bonds and π⋯π interactions in a three-dimensional supramolecular network.
