Abstract

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—H⋯N hydrogen bonds are observed between the 4-hy­droxy­benzoate anions and the uncoordinated 1,10-phenanthroline mol­ecules.
