将粉末状 (NH4) 2 [OsCl6] 缓慢添加到 2 2·20 中，然后回流 10 小时，得到 [Os (N-H3) 5 (N2)] C12 和顺式-[0s (NH3) 4 (N2) 2] Cl2 的混合物。混合物与2 2·20 的进一步反应产生约90％产率的[Os(NH 3 ) 5 (N 2 )] Cl 2 。当进行反向添加时（即，将 2 2·20 添加到 (NH4) 2 [OsCl6] 中），随后发生的放热反应会产生以前未知的氮桥络合物 [(NH3) 5OsNOs (NH3) 5] Cl5'H20，产率约 90%。该化合物是高产率制备各种 iraŦí、traní-[X (NH3) 4OsNOs (NH3) 4X]"+ 配合物的便捷原料。[(NH3) 5GsN0s (NH3) 5] Cl5'H20 的电子吸收光谱已借助 MO 图确定，并与 Ru 和 Ru 的其他 ĩ-3-配合物的光谱进行了比较。奥斯。
Slow addition of powdered (NH4) 2 [OsCl6] to 2 2· 20, followed by refluxing for 10 h, results in a mixture of [Os (N-H3) 5 (N2)] C12 and cis-[0s (NH3) 4 (N2) 2] Cl2. Further reaction of the mixturewith 2 2· 20 results in~ 90% yield of [Os (NH3) 5 (N2)] Cl2. When the reverse addition is performed (ie 2 2· 20 is addedto (NH4) 2 [OsC16]), the very exothermic reaction that follows produces the previously unknown nitrido-bridged complex [(NH3) 5OsNOs (NH3) 5] Cl5'H20 in~ 90% yield. This compound is a convenient starting material for the preparation of a variety of íraŦí, traní-[X (NH3) 4OsNOs (NH3) 4X]"+ complexes in high yields. The electronic absorption spectrum of [(NH3) 5GsN0s (NH3) 5] Cl5'H20 has been assigned with the aid of a MO diagram and a comparison of its spectrumwith those of other ĩ-3-complexes of Ru and Os.
