The mononuclear title complex, [Ce(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], is isostructural to other related lanthanide structures. The Ce atom is in a pseudo-bicapped square-anti-prismatic geometry formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and by six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from a nitrate anion. π-π stacking inter-actions between phen and DHB ligands [centroid-centroid distances = 3.513 (3) and 3.762 (2) Å] and phen and phen ligands [face-to-face separation = 3.423 (7) 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[Ce(C₇H₅O₃)₂(NO₃)(C₁₂H₈N₂)₂]与其他相关镧系元素结构同构。铈原子处于由来自两个螯合的1,10 - 菲咯啉（phen）配体的四个氮原子以及六个氧原子形成的伪双帽方反棱柱几何构型中，其中四个氧原子来自两个2,6 - 二羟基苯甲酸酯（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 = 3.513(3) 和3.762(2) Å]以及phen与phen配体之间的π - π堆积相互作用[面对面间距 = 3.423(7) Å]稳定了晶体结构。在DHB配体中观察到分子内O - H⋯O氢键。
