The title complex, [Pr(C 7 H 5 O 3 ) 2 (NO 3 )(C 12 H 8 N 2 )]·2C 12 H 8 N 2 , has a polymeric chain structure, with two uncoordinated 1,10-phenanthroline mol­ecules in the lattice. The Pr III  centre has a monocapped square-anti­prismatic coordination geometry, comprised of two N atoms from one chelating 1,10-phenanthroline ligand, four carboxyl­ate O atoms from four 4-hy­droxy­benzoate anions and three O atoms from two nitrate anions. The 4-hy­droxy­benzoate and nitrate anions function as μ 2 -bridging ligands and link the Pr III  ions into a one-dimensional chain structure along the  c  axis. Inter­molecular O—H⋯N hydrogen bonds are observed between the 4-hy­droxy­benzoate anions and the uncoordinated 1,10-phenanthroline mol­ecules.
