The reaction of the glycolate complex O2)·(py)2 (1) with (C6F5)2Zn·(py)2 (2) afforded the first perfluorophenyl compound of osmium. The octahedral geometry of the title compound (η1-C6F5)2OsO2·(py)2 (3), containing a linear osmyl group OsO2}2+, was determined by single crystal X-ray diffraction methods. The strikingly high stability of the bis(pyridine) complex, which sublimes at 230°C without decomposition

酯配合物O 2)·(py)2(1)与(C 6 F 5)2 Zn·(py)2(2)的反应提供了first的第一
全氟苯基化合物。标题化合物的八面体几何构(η 1 -C 6 ˚F 5)2的OsO 2 ·(PY)2(3),其包含线性osmyl组的OsO 2 } 2+通过单晶X射线衍射法测定。双(
吡啶)配合物在230°C升华而不分解的惊人的高稳定性是由于存在强吸电子,与σ键相连的
全氟苯基的缘故。
