The cluster complex Ru(5)(CO)(12)(C(6)H(6))(mu(5)-C), 1, undergoes multiple addition reactions with Ph(3)SnH to yield two new bimetallic cluster complexes: Ru(5)(CO)(8)(mu-SnPh(2))(4)(C(6)H(6))(mu(5)-C), 2, 2% yield, and Ru(5)(CO)(7)(mu-SnPh(2))(4)(SnPh(3))(C(6)H(6))(mu(5)-C)(mu-H), 3, 26% yield, containing four and five tin ligands, respectively. Both compounds consist of a square pyramidal Ru(5) cluster with an interstitial carbido ligand and bridging SnPh(2) groups located across each of the four edges of the base of the Ru(5) square pyramid. Compound 3 contains an additional SnPh(3) group terminally coordinated to one of the ruthenium atoms in the square base.
簇合物 Ru(5)(CO)(12)(C(6)H(6))(μ(5)-C)，即 1，与 Ph(3)SnH 发生多次加成反应，生成两种新的双金属簇合物：Ru(5)(CO)(8)(μ-SnPh(2))(4)(C(6)H(6))(μ(5)-C)，即 2，产率为 2%；以及 Ru(5)(CO)(7)(μ-SnPh(2))(4)(SnPh(3))(C(6)H(6))(μ(5)-C)(μ-H)，即 3，产率为 26%，它们分别含有四个和五个锡配体。两种化合物均由一个具有间隙碳化物配体的正方锥 Ru(5)簇以及位于 Ru(5)正方锥底面四条边每条边上的桥联 SnPh(2)基团组成。化合物 3 含有一个额外的 SnPh(3)基团，该基团末端配位至正方底面中的一个钌原子上。
