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 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 μ₂-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.

Experimental top

Each reagent was commercially available and of analytical grade. Pr(NO₃)₃^.6H₂O (0.217 g, 0.5 mmol), p-Hydroxybenzoic acid (0.069 g 0.5 mmol), 1, 10-phenanthroline (0.090 g, 0.5 mmol) and NaHCO₃ (0.042 g, 0.5 mmol) were dissolved in water-ethanol solution (10 ml, 5:5). The solution was refluxed for 4 h, and filtered after cooling to room temperature. White single crystals were obtained from the filtrate after 7 days.

Experimental. CrysAlisPro, Oxford Diffraction Ltd., Version 1.171.34.36 Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
