All change: Complete ligand exchange through the hydrogenation of [Ru(eta(4)-cod)(eta(6)-cot)] in the presence of GaCp* under mild conditions leads to the title complex featuring a "naked" gallium atom bridging two ruthenium centers (see structure: C white, Ga blue, Ru red). This cluster can be considered as a trapped intermediate on the way to mixed-metal nanoparticles; cot = 1,3,5-cyclooctatriene; cod = 1,5-cyclooctadiene, Cp* = C(5)Me(5).
全变了
在温和条件下，[Ru(η⁴ - cod)(η⁶ - cot)]在GaCp存在下通过氢化进行完全配体交换，生成了具有一个“裸露”镓原子桥连两个钌中心的标题配合物（见结构：C白色，Ga蓝色，Ru红色）。该簇合物可被视为通往混合金属纳米颗粒途中的一个捕获中间体；cot = 1,3,5 - 环辛三烯；cod = 1,5 - 环辛二烯，Cp = C₅Me₅ 。
