or Br). Heating [Os2X2(CO)8](X = Cl or Br) in n-heptane solution affords the hexacarbonyl compounds [Os2X2(CO)6]. The reactions of tin tetrachloride with [Os(CO)4}nH2](n= 1–3) are reported: for n= 1 or 2, the compounds [Os(CO)4}n H(SnCl3)](n= 1 or 2) have been isolated. The reaction of [Os2(CO)8H2] with triphenylphosphine yields the compounds [Os2(CO)7H2(PPh3)], [Os2(CO)6H2(PPh3)2], [Os(CO)4(PPh3)]
[Os(CO)4 } n H 2 ](n = 2或3)与四卤化碳的反应产生相应的二卤化物[Os(CO)4 } n X 2 ](X = Cl或Br)。在
正庚烷溶液中加热[Os 2 X 2(CO)8 ](X = Cl或Br),得到六羰基化合物[Os 2 X 2(CO)6 ]。据报道
四氯化锡与[Os(CO)4 } n H 2 ](n = 1-3)的反应:对于n = 1或2,化合物[Os(CO)4 }已分离出n H(SnCl 3)](n= 1或2)。[Os 2(CO) 8 H 2 ]与
三苯基膦反应生成化合物[Os 2(CO) 7 H 2(PPh 3)],[Os 2(CO) 6 H 2(PPh 3) 2 ],[ Os(CO) 4(PPh 3)]和[Os(CO) 3 H 2(PPh 3)]。[Os 3(CO) 12 H 2 ]或[Os 2的热解(CO)8 H 2 ]给出
氢化物[Os(CO)4
