In the title compound, [Eu2(C6H5NO3)2(C2O4)3(H2O)4]n, the EuIII atom is bonded to one O atom from a monodentate 5-hydroxypyridin-1-ium-3-carboxylate ligand, six O atoms from three oxalate ligands and two water molecules, exhibiting a highly distorted tricapped trigonal geometry. Three independent oxalate ligands, each lying on an inversion center, bridge the EuIII atoms, forming a brickwall-like layer parallel to (001), which is stabilized by intralayer O-H...O hydrogen bonds. The layers are further linked through interlayer O-H...O and N-H...O hydrogen bonds and [pi]-[pi] interactions between the pyridine rings [centroid-centroid distance = 3.5741 (14) Å] into a three-dimensional supramolecular network.
