The mononuclear title complex, [Pr(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], is isostructural with related complexes of other lanthanides. The Pr(III) atom is in a pseudo-bicapped square-anti-prismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from nitrate anions. π-π stacking inter-actions between the phen and DHB ligands [centroid-centroid distances = 3.518 (2) and 3.778 (2) Å] and the phen and phen ligands [face-to-face separation = 3.427 (6) Å] of adjacent complexes stabilize the crystal structure. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.
单核标题配合物[Pr(C₇H₅O₃)₂(NO₃)(C₁₂H₈N₂)₂]与其他镧系元素的相关配合物同构。Pr(III)原子处于假双帽方反棱柱几何构型，由来自两个螯合的1,10 - 菲咯啉（phen）配体的四个N原子和六个O原子构成，其中四个O原子来自两个2,6 - 二羟基苯甲酸（DHB）配体，另外两个来自硝酸根阴离子。相邻配合物的phen与DHB配体之间的π - π堆积相互作用[质心 - 质心距离 = 3.518(2) 和3.778(2) Å]以及phen与phen配体之间的[面对面间距 = 3.427(6) Å]稳定了晶体结构。在DHB配体中观察到分子内O - H⋯O氢键。
