In the title compound, [Pr(NO3)3(C10H12N2O)2], the PrIII ion is ten-coordinated by two N and two O atoms from two bidentate 3-(dimethylamino)-1-(2-pyridyl)prop-2-en-1-one ligands and by six O atoms from three nitrate anions in a distorted bicapped square-antiprismatic geometry. An extensive three-dimensional network of weak intermolecular C—H⋯O hydrogen bonds consolidates the crystal packing.
