μ_3-η~2-Aminophosphino Containing Cluster HRu_3[μ_3-η~2-P(NEt_2)_2](CO)_9—Synthesis and Structure

本文用 Ru_3(CO)_(12)和二(二乙胺)氯化膦(Er_2N)_2PCl 在较温和条件下反应得到了一个具有新结构和新配位方式的三核簇合物 HRu_3{μ_3-η~2-P(NEt_2)_2}(CO)_3.该簇合物的结构特点是由于配体中磷原子和一个氮原子组成桥参与配位而形成一千五员 Ru_3PN 稳定骨架结构,我们对该簇合物进行了元素分析和 IR,HNMR,MS 表征工作,并进行了

The reaction of Ru_3(CO)_(12) with bis(diethylamino)chlorophosphine gives the trinuclear cluster HRu_3 {μ_2-η~2-P(NEt_2)_2}(CO)_9 with new molecular structure and novel coordination mode.The structural feature of this cluster consists a new kind of birdge,in which the birdgod ligand P(NEt_2)_2 uses its P aton as u_2, 3e donor and together with one of its N atoms as 2e donor,and thus form a five—membered Ru_3PN cage —like skeleton.The cluster have been characterized by IR,HNMR and MS spectrometries,and its struc- ture detcrminated by X—ray four cycle diffractometer
