Abstract: The title coordination polymer, poly[diaqua(1,10-phenanthroline)(₃-pyrazole-3,5-dicarboxylato)tricopper(II)], [Cu₃(C₅HN₂O₄)₂(C₁₂H₈N₂)₂(H₂O)₂]_n, was hydrothermally synthesized and structurally characterized. It consists of linear trinuclear copper(II) clusters of [Cu₃(pdc)₂(phen)₂(H₂O)₂] units (H₃pdc = pyrazole-3,5-dicarboxylic acid and phen = 1,10-phenanthroline), in which two pdc^3- ligands chelate three Cu^II ions with the central Cu^II ion on an inversion center. An infinite two-dimensional sheet structure is constructed by connecting adjacent linear trinuclear copper(II) units through coordination bonds between the central Cu^II atom and an O atom of the carboxylate group coordinated to the terminal Cu^II atom from the pdc^3- ligand.
