在氢气保护下，用ＲｕＣｌ２（ＰＰｈ３）３和ＮａＢＨ４于乙醇和苯混合溶液（４∶３）中室温下反应，成功地合成了新的双核钌多氢化物Ｒｕ２Ｈ４（ＣＯ）（ＰＰｈ３）４。低温原位ＦＴＩＲ光谱和Ｘ－ｒａｙ单晶结构分析表明，获得的双核钌多氢化物是含一个配位ＣＯ，四个配位ＰＰｈ３，具有Ｒｕ－Ｒｕ和氢桥键的新簇合物。
The new binuclear ruthenium polyhydride Ru2H4 (CO) (PPh3) 4 was successfully synthesized by the reaction of RuCl2 (PPh3) 3 and NaBH4 in a mixture of ethanol and benzene (4: 3) at room temperature under the protection of hydrogen. In situ FTIR spectroscopy and X-ray single crystal structure analysis showed that the obtained binuclear ruthenium polyhydride is a new cluster containing one coordination CO, four coordination PPh3, Ru-Ru and hydrogen bridges.
