2,4-二氯苯甲酸和4,4′-联吡啶与Ag⁺的单晶合成和结构

Crystal Syntheses and Structures of Ag⁺ Complex with 2,4-Dichlorobenzoic Acid and 4,4'-Bipyridyl Ligands

摘要: 本文以2,4-二氯苯甲酸、4,4'-联吡啶和硝酸银为原料，采用自然挥发法制备了新的配合物[C₂₇H₁₉Ag₂Cl₂N₅O₅]_n，并对其进行了元素分析、红外光谱和X-射线单晶衍射的表征。结果表明，配合物为一维结构，其中，配合物中存在C-H···O、C-H···Cl、C-H···π和π···π分子间作用，并以此形成了3D超分子结构。

Abstract: New coordination complex [C₂₇H₁₉Ag₂Cl₂N₅O₅]_n was synthesized by natural evaporation methods using 2,4-Dichlorobenzoic acid, 4,4'-dipyridyl and AgNO₃ as raw materials. And the complex was characterized by elemental analysis, and FT-IR and X-ray single-crystal structure analysis. The result shows that the complex is one-dimensional structure. The there are C-H···O, C-H···Cl, C-H···π and π···π intermolecular interaction contributing to 3D supramolecular structure.
