Abstract

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 mol-ecules in the lattice. The Pr(III) centre has a monocapped square-anti-prismatic coordination geometry, comprised of two N atoms from one chelating 1,10-phenanthroline ligand, four carboxyl-ate O atoms from four 4-hy-droxy-benzoate anions and three O atoms from two nitrate anions. The 4-hy-droxy-benzoate 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. Inter-molecular O-H⋯N hydrogen bonds are observed between the 4-hy-droxy-benzoate anions and the uncoordinated 1,10-phenanthroline mol-ecules.

摘要

标题配合物[Pr(C₇H₅O₃)₂(NO₃)(C₁₂H₈N₂)]·2C₁₂H₈N₂具有聚合链结构，晶格中有两个未配位的1,10 - 菲咯啉分子。Pr(III)中心具有单帽方反棱柱配位几何构型，由一个螯合的1,10 - 菲咯啉配体的两个N原子、四个4 - 羟基苯甲酸根阴离子的四个羧酸根O原子以及两个硝酸根阴离子的三个O原子组成。4 - 羟基苯甲酸根和硝酸根阴离子作为μ₂ - 桥联配体，将Pr(III)离子沿c轴连接成一维链结构。在4 - 羟基苯甲酸根阴离子与未配位的1,10 - 菲咯啉分子之间观察到分子间O - H⋯N氢键。
