Abstract: The reaction of praseodymium(III) trichloroacetate with 1,10-phenanthroline (phen), acetic acid and 8-hydroxyquinoline gives the title centrosymmetric complex, [Pr₂(C₂Cl₃O₂)₄(C₂H₃O₂)₂(C₁₂H₈N₂)₂(H₂O)₂]·2C₃H₇NO. The geometry around the Pr^III ion corresponds to a monocapped square antiprism. Interestingly, the carboxylate groups coordinate in three different modes, viz. monodentate, bridging and bridging-chelating. In the crystal structure, there are weak intermolecular ClCl and --stacking interactions.
