利用配体取代反应合成了四种含双二苯基膦甲烷 (dppm)的双铜 配合物 [Cu2 (dppm) 2 L2 ](NO3) 2 (配体L分别是 2 ,2’ 联吡啶 (1)、邻菲咯啉 (2 )、2 ,9 二甲基 邻菲咯啉 (3)、吡啶 (4 ) ],并经核磁、热分析、光电子能谱等方法表征了配合物的性质。配合物 (1)的晶体结构显示 ,dppm作为桥式双齿配体、联吡啶作为双齿配体分别与铜原子形成四面体配位结构 ,硝酸根离子位于配合物外界
Four double copper complexes with bisdiphenylphosphine methane (dppm) [Cu2 (dppm) 2 L2] (NO3) 2 were synthesized by ligand substitution reaction ), Phenanthroline (2), 2,9-dimethylphenanthroline (3) and pyridine (4)] were synthesized and characterized by means of NMR, thermal analysis and photoelectron spectroscopy. The crystal structure of (1) shows that dppm acts as a bridged bidentate ligand and bipyridine acts as a bidentate ligand to form a tetrahedral coordination structure with the copper atom respectively. The nitrate ion is located outside the complex
