Attempts to prepare Fe(CO)5 (+) from Ag[Al(OR(F) )4 ] (R(F) =C(CF3 )3 ) and Fe(CO)5 in CH2 Cl2 yielded the first complex of a neutral metal carbonyl bound to a simple metal cation. The Ag[Fe(CO)5 ]2 (+) cation consists of two Fe(CO)5 molecules coordinating Ag(+) in an almost linear fashion. The ν(CO) modes are blue-shifted compared to Fe(CO)5 , with one band above 2143 cm(-1) indicating that back-bonding is heavily decreased in the Ag[Fe(CO)5 ]2 (+) cation.
试图从 Ag[Al(OR(F) )4 ]（R(F) =C(CF3 )3 ）和 Fe(CO)5 在 CH2 Cl2 中制备 Fe(CO)5 (+)，得到了第一个中性金属羰基与简单金属阳离子键合的配合物。Ag[Fe(CO)5 ]2 (+)阳离子由两个 Fe(CO)5 分子以近乎线性的方式配位 Ag(+)组成。与 Fe(CO)5 相比，ν(CO)模式发生蓝移，一个频带高于 2143 cm(-1)表明在 Ag[Fe(CO)5 ]2 (+)阳离子中，反馈键合大大减少。
