摘要
利用相应的羧酸和 Ag2O 制备了一系列含有羧酸配体的银(I)和铜(I)配合物。这些化合物通过各种光谱方法和 X 射线衍射法进行了表征。在固态下,银(I)盐是基于二核银物种与桥接羧酸配体的配位聚合物。这些银盐与 Ph3P 反应生成四配位的四面体双(膦)络合物。通过羧酸铜(II)与 Ph3P 的还原反应,制备出了类似的双(膦)铜(I)化合物。通过 TGA/DSC 测量研究了分解温度和热分解产物。金属化合物在 206 至 338 °C 的温度范围内分解为各自的金属(银或铜)。
Silver(I) and Copper(I) Complexes of Dicarboxylic Acid Derivatives: Synthesis, Characterization and Thermal Studies
A family of silver(I) and copper(I) complexes containing carboxylate ligands were prepared from the corresponding carboxylic acids and Ag2O. The compounds were characterized by various spectroscopic methods and X-ray diffraction. In the solid state, the silver(I) salts are coordination polymers based on dinuclear silver species with bridging carboxylate ligands. The reaction of these silver salts with Ph3P gives four-coordinate, tetrahedral bis(phosphine) complexes. Analogous copper(I) bis(phosphine) compounds were prepared by the reduction of copper(II) carboxylates with Ph3P. Decomposition temperatures and thermal decomposition products were studied by TGA/DSC measurements. The metal compounds decomposed cleanly to their respective metals (silver or copper) at temperatures ranging from 206 to 338 °C.
