Manganese Carbonyl

Chemical Formula: Mn2(CO)10
CAS: 10170-69-1

Manganese carbonyl (Mn2(CO)10) is a yellow crystalline solid composed of two manganese atoms bridged by a carbonyl ligand. It is sensitive to air and is a widely used source of zero-valent manganese in organometallic chemistry. Due to its strong metal-carbonyl bond and unique reactivity, it is widely used as a homogeneous catalyst, a precursor for manganese complexes, and an active intermediate in organic synthesis and materials science.

Manganese Carbonyl Key Features

Excellent catalytic performance

As a metal precursor in homogeneous catalytic reactions, manganese carbonyl exhibits good activity and selectivity in organic carbonylation, reduction, and olefin conversion.

Unique photosensitivity

Mn2(CO)10 exhibits photochemical activity, and under illumination of specific wavelengths of light, it can undergo homolytic bond cleavage to generate highly reactive ·Mn(CO)₅ free radicals, which provides the possibility for photo-initiated chemical reactions and material synthesis.

Highly efficient catalytic activity

As a catalyst precursor, this compound can efficiently promote a variety of reactions in organic synthesis. For example, it can be used to prepare polynuclear selenium manganese carbonyl cluster complexes and exhibits good catalytic performance in reactions such as hydroformylation.

Important source of manganese metal

As a typical zero-valent metal carbonyl compound, manganese carbonyl is an ideal source for introducing manganese metal into the system and is widely used in the synthesis of other manganese complexes and functional materials.

Manganese Carbonyl Main Applications

Homogeneous catalysis

Acts as a catalyst or catalyst precursor in hydroformylation, carbonylation, hydrosilylation, and C–H activation reactions.

Organometallic synthesis

Source of Mn(0) for preparing specialized manganese coordination complexes with tailored reactivity.

Fine chemical & pharmaceutical synthesis

Facilitates selective transformations, such as aldehyde formation from alkenes and CO insertion reactions.

Thin film & nanomaterial precursor

Used in chemical vapor deposition (CVD) and metal–organic chemical vapor deposition (MOCVD) for depositing manganese-containing films in electronics and catalysis.

Academic research

Common in mechanistic studies of metal carbonyl cluster chemistry and as a teaching compound for organometallic structure and bonding.

Precautions

  1. Mn2(CO)10 is sensitive to light and air; exposure may cause it to darken and decompose. It is recommended to store it away from light and operate under an inert gas atmosphere (such as argon or nitrogen). The recommended storage temperature is 2-8℃, and contact with oxidants should be avoided.

  2. This substance is toxic; skin contact or inhalation can cause poisoning. When handling it, be sure to wear appropriate personal protective equipment and conduct the operation in a well-ventilated environment.

  3. If skin contact occurs, immediately flush with plenty of water for at least 15 minutes. If inhaled, move the patient to fresh air and seek immediate medical attention.

FAQ

1. What catalytic reactions can manganese carbonyl be used in?

This compound is commonly used in carbonylation, reduction, photocatalysis, and C–C bond formation reactions. It can also serve as a precursor for other manganese complexes.


2. Can it be dissolved in water?

No. Mn2(CO)10 is insoluble in water and will decompose. Organic solvents such as ether, benzene, or THF should be used.
