In the title compound, [Pr(NO(3))(3)(C(10)H(12)N(2)O)(2)], the Pr(III) ion is ten-coordinated by two N and two O atoms from two bidentate 3-(dimethyl-amino)-1-(2-pyrid-yl)prop-2-en-1-one ligands and by six O atoms from three nitrate anions in a distorted bicapped square-anti-prismatic geometry. An extensive three-dimensional network of weak inter-molecular C-H⋯O hydrogen bonds consolidates the crystal packing.

The polymeric nature of the compound involves two non-equivalent 4,4'-bipyridyl ligands acting as almost orthogonal bridges joining the metal coordination Jahn-Teller-distorted octahedra, and forming ladders packed under the influence of hydrogen bonds involving the uncoordinated amino group of the p-aminobenzoate ligand, the NO(3)(-) anion and the water molecules.
