pentaethylcyclophosphine, (EtP)5, with triosmium cluster [Os3(CO)10(NCMe)2] in dichloromethane at room temperature afforded [Os3(CO)101,2-(EtP)5}] (1) with an unusual 1,2-chelation mode for the cyclophosphine. The same reactants at a higher temperature gave rise to [Os3(CO)101,3-(EtP)5}] (2). Treatment of the same ligand with triosmium cluster [Os3(CO)11(NCMe)] yielded several new clusters [Os3(CO)11(EtP)5}] (3)
摘要 五乙基环膦 (EtP)5 与三锇簇 [Os3(CO)10(NCMe)2] 在二氯甲烷中在室温下反应得到 [Os3(CO)101,2-(EtP)5}] (1)环膦具有不寻常的 1,2-螯合模式。相同反应物在较高温度下生成 [Os3(CO)101,3-(EtP)5}] (2)。用三锇簇 [Os3(CO)11(NCMe)] 处理相同的配体产生了几个新的簇 [Os3(CO)11(EtP)5}] (3), [Os3(CO)11}21, 3-(EtP)5}] (4), [Os3(CO)11}21,,2-(EtP)5}] (5), [Os3(CO)101,2,3- (EtP)5}Os3(CO)11] (6) 和 [Os3(CO)101,2,4-(EtP)5}Os3(CO)11] (7)。
