摘要
dppe配体按文献所示方法自行合成。在10ml甲醇中先后溶入0.05g(0.29mmol)AgNO_3和0.23g(0.58mmol)dppe。将过滤后的清液半敞开静置14天,即析出棱形无色晶体,再以甲醇重结晶。晶体由于溶剂化而极易风化成白色粉末。
The crystal of Ag2(dppe)4(NO3·CH3OH)2 is monoclinic, space group P21 / n, with a=14.741, b= 19.042, c= 18.982A;β = 110.66°. The molecule has a 2, symmetry axis. The four dppe ligands are coordinated in two ways, two ligands bridging the two silver atoms, and the other two ligands chelate to each silver atom separately to form two penta-cycles.
