In the title complex, [Pb(NO(3))(2)(C(14)H(12)N(2))(2)], the lead ion is chelated by two 2,9-dimethyl-1,10-phenanthroline (dmphen) ligands and two nitrate anions in a slightly distorted square-anti-prismatic geometry. Intra- and inter-molecular π-π stacking is present in the crystal structure, and the centroid-centroid distances between the benzene and pyridine rings of adjacent dmphen ligands are 3.492 (3) and 3.592 (3) Å, respectively. Inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions help to stabilize the crystal structure.
在标题配合物[Pb(NO₃)₂(C₁₄H₁₂N₂)₂]中,铅离子由两个2,9 - 二甲基 - 1,10 - 菲咯啉(dmphen)配体和两个硝酸根阴离子以略微扭曲的四方反棱柱几何构型螯合。晶体结构中存在分子内和分子间的π - π堆积,相邻dmphen配体的苯环和吡啶环之间的质心 - 质心距离分别为3.492 (3) Å和3.592 (3) Å。分子间的C - H⋯O氢键和C - H⋯π相互作用有助于稳定晶体结构。
