N2 - The reaction of the glycolate complex O2Os(OCH2CH2O)·(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, is due to the presence of the strongly electron withdrawing, σ-bonded perfluorophenyl groups.
