铜（Ｉ）配合物由于其变化奇异的结构，性质及配位数而引起化学工作者的广泛兴趣。众所周知，四电子供体双二苯基膦甲烷（ｄｐｐｍ）适宜在近距离内与两个金属原子同时配位，容易形成八员环的二聚体Ｍ２Ｐ４Ｃ２［１］，因而是桥联两个低氧化态过渡金属的最佳选择，由于在Ｍ２
Copper (I) complexes have attracted widespread interest among chemists due to their singular structures, properties and coordination numbers. As we all know, the four electron donor bisdiphenylphosphine methane (dppm) is suitable for close coordination with the two metal atoms at the same time, easy to form a eight-membered ring dimer M2P4C2 [1], thus bridging two low Oxidation state transition metal is the best choice due to the M2
