The complex [Pb(phen)(4-NB)(CH 3 COO)] of lead(II) was prepared and characterized by means of elemental analysis, FT-IR, and single crystal X-ray analysis, where phen = 1,10-phenanthroline, 4-NB = 4-nitrobenzoate. The single crystal X-ray analysis indicates that the complex is a monomeric species, including two carboxylate ligands, and adopts a hemidirected structure. It is further extended by intermolecular C−H⋯O hydrogen bonds, π–π interactions and secondary Pb⋯O interactions to form two-dimensional supramolecular architecture.

一种由 1,10-菲咯啉和两个羧酸盐配体构建的新型 Pb(II) 配合物的合成和晶体结构

制备了铅(II)的配合物[Pb(phen)(4-NB)(CH 3 COO)]，并通过元素分析、FT-IR和单晶X射线分析对其进行了表征，其中phen = 1， 10-菲咯啉，4-NB = 4-硝基苯甲酸酯。单晶X射线分析表明，该配合物是一种单体物质，包括两个羧酸盐配体，并采用半定向结构。它通过分子间 C−H⋯O 氢键、π-π 相互作用和二级 Pb⋯O 相互作用进一步扩展，形成二维超分子结构。
