The title complex, [Pr(C7H5O3)2(NO3)(C12H8N2)]·2C12H8N2, has a polymeric chain structure, with two uncoordinated 1,10-phenanthroline molecules in the lattice. The PrIII 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 μ2-bridging ligands and link the PrIII ions into a one-dimensional chain structure along the c axis. Intermolecular O—HN hydrogen bonds are observed between the 4-hydroxybenzoate anions and the uncoordinated 1,10-phenanthroline molecules.

In the title compound, C22H15Cl2NO, the terminal chlorobenzene rings are oriented at 44.51 (15) and 86.06 (17)° with respect to the central polysubstituted benzene ring, and make a dihedral angle of 49.48 (17)°with each other. In the crystal, molecules are linked by weak C—HO and C—HN interactions.
