Abstract: The europium^III ion in the title compound, [Eu₂(C₈H₆NO₂)₆(C₁₂H₈N₂)₂]·5H₂O, is coordinated by seven carboxylate O atoms and two N atoms from one phenanthroline molecule. The carboxylate groups of 3-(3-pyridyl)acrylate link pairs of europium(III) ions, forming centrosymmetric dinuclear units, which further assemble into a sheet parallel to the (001) plane through hydrogen-bonding interactions involving the uncoordinated water molecules. One water molecule is disordered.
