Pentacarbonylhydridomanganese is an organometallic compound with formula HMn(CO)5. This compound is one of the most stable "first-row" transition metal hydrides.
==Preparation==
It was first reported in 1931.〔 Of the several ways to produce this compound,〔 is the protonation of the pentacarbonyl manganate anion. The latter is formed from reduction of dimanganese decacarbonyl (Mn(CO)5)2. The reaction is shown below.
:LiHB(C2H5)3 (Superhydride) + ½Mn2(CO)10 → Li() + ½H2 + (C2H5)3B
:Li() + CF3SO3H → HMn(CO)5 +
Salts of can be isolated as crystalline (μ-nitrido—bis-(triphenylphosphorus)) salt, which is smoothly protonated by CF3SO3H.〔
:PPN() + CF3SO3H → HMn(CO)5 +
This compound can also be formed by the reaction of a solution of pentacarbonyl(trimethylsilyl)manganese with water.〔 The reaction is shown below.
:2(CO)5MnSiMe3 + H2O → HMn(CO)5 + Me3SiOSiMe3
