【摘要】 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更多还原

【Abstract】 Binuclear copper Ⅰ complexes [Cu(dppm)L] 2(NO 3) 2 (L=2,2’ bipy(1),phen(2),2,9 Me2 phen(3), pyridine(4), dppm=Ph 2PCH 2PPh 2) have been synthesized by ligands replacement reaction and characterized by specific elemental analyses, TG, 31 P NMR, and XPS have also been measured. X Ray crystal structure of complex (1) shows that dppm and 2,2’ bipy coordinate as bridging bidentate ligand and bidentate ligand to the Cu Ⅰ atoms with tetrahedral structure, andNO 3 behaves as free ion in the newly prepared binuclear copper Ⅰ complexes. $$$$更多还原
